Transform the uploaded photograph into a highly detailed, expressive, hand-drawn mixed-media illustration that precisely matches the artistic style, sketch texture, colour balance, and visual character of the provided reference image. Use the reference image ONLY as an artistic style guide. Use the newly uploaded photograph as the sole source for the subject, identity, composition, pose, objects, environment, perspective, and framing. 1. EXACT ARTISTIC STYLE Recreate the appearance of a rough, traditional architectural sketchbook illustration made using graphite pencils, charcoal, fine ink lines, and subtle coloured-pencil or watercolor washes. The image should look manually drawn by an experienced artist, with dense crosshatching, scratchy pencil strokes, overlapping sketch lines, irregular contours, loose construction marks, and naturally imperfect shading. Maintain the original photograph's realistic structure beneath the hand-drawn treatment. The result must look like an authentic scanned illustration on lightly textured drawing paper, NOT a simple pencil filter, polished digital painting, cartoon, anime, or vector illustration. 2. COLOUR CORRECTION — MOST IMPORTANT Preserve the original photograph's natural colours and use them as the primary colour reference. Do NOT apply an overall yellow, orange, sepia, or golden filter. Use a neutral, slightly warm, naturally balanced colour palette inspired by the reference image: - Background: Preserve the original wall, sky, buildings, and environmental colours. Use natural cement grey, cool grey, soft off-white, and subtle warm beige where appropriate. - Skin: Retain the subject's original skin tone with natural undertones. Use realistic light and shadow without turning the skin yellow, orange, or excessively brown. - Clothing: Preserve the original garment colours. Render burgundy as rich, muted burgundy; blue as natural blue; black as deep charcoal; and white or cream as soft neutral ivory. - Objects: Preserve the recognisable colours of all original objects. Red objects should remain recognisably red, green objects naturally green, and other coloured objects faithful to the photograph. - Shadows: Use graphite grey, charcoal, muted brown, and subtle cool-grey undertones rather than covering everything with brown or yellow. - Paper: Use a subtle off-white or pale neutral-grey paper tone with very fine natural texture. Avoid heavily yellowed parchment. Maintain the original colour relationships while translating them into a traditional hand-drawn illustration. 3. SLIGHT SATURATION AND COLOUR ENHANCEMENT Apply a subtle increase in colour richness compared with a faded vintage sketch. Enhance the original colours by approximately 10–15% in perceived saturation, keeping the result natural, restrained, and sophisticated. Make important colours slightly more noticeable without making them vivid or artificially bright. Preserve the depth of dark clothing, the richness of naturally coloured objects, and the separation between the subject and background. Use gentle tonal contrast and clear colour separation. Keep highlights clean, shadows detailed, and midtones naturally balanced. The final image should have slightly richer colours than an ordinary faded sketch while retaining the muted, artistic appearance of the reference. Colour priority: original photograph's colours first, reference sketch's colour treatment second. 4. SIGNATURE GRAPHITE TEXTURE Make the visible hand-drawn pencil texture one of the strongest features of the image. Apply dense but irregular graphite crosshatching, fine diagonal strokes, overlapping pencil lines, scratchy shading, spontaneous scribbles, broken contours, and subtle charcoal marks throughout the entire image. Build shadows from multiple directional pencil strokes rather than smooth digital gradients. Use: - Fine, delicate strokes for facial features and small details. - Dense, dark crosshatching for hair, deep shadows, and dark clothing. - Loose, expressive lines for walls, floors, buildings, and background surfaces. - Layered directional strokes to define fabric folds, object shapes, and architectural perspective. - Subtle graphite smudging and visible pencil pressure variations for authenticity. Keep the pencil marks individually visible. Avoid excessive digital smoothness, uniform textures, artificial outlines, and an overly clean finish. Allow some sketch lines to overlap or extend slightly beyond contours, creating the natural imperfections of a hand-drawn illustration. 5. LIGHTING AND SHADING Preserve the original photograph's lighting direction, natural highlights, and shadow placement. Use soft, realistic illumination with balanced contrast. Create highlights through exposed paper, delicate light pencil marks, and subtle coloured washes. Build shadows using layered graphite, charcoal, and fine crosshatching. Retain detail in both dark and bright areas. Avoid dramatic cinematic relighting, excessive darkness, artificial glow, strong orange lighting, and smooth airbrushed gradients. 6. BACKGROUND AND ENVIRONMENT Preserve the original background exactly as it appears in the uploaded photograph. Reinterpret walls, floors, stairs, roads, trees, vehicles, furniture, buildings, and other environmental elements using loose architectural sketch lines, irregular pencil shading, visible perspective marks, and textured crosshatching. Maintain the original geometry, perspective, object positions, and spatial relationships. Use slightly looser sketchwork in less important background areas, but retain enough detail to make the original location recognisable. Do not replace the background with plain paper, invent new architectural elements, or remove existing details. 7. SUBJECT AND IDENTITY PRESERVATION Preserve the exact identity and appearance of the person in the uploaded photograph. Maintain the original: - Facial structure and facial features. - Hairstyle, hair texture, and hair silhouette. - Skin tone and natural complexion. - Facial expression and direction of gaze. - Body proportions and anatomy. - Pose, posture, and hand positions. - Clothing, garment colours, folds, and accessories. - Footwear, jewellery, watches, and other visible details. Translate these features into realistic hand-drawn pencil and ink work without beautifying, reshaping, or redesigning the person. Keep the subject clearly recognisable and anatomically accurate. Do not change the person's face, body shape, clothing, or pose. 8. PAPER TEXTURE AND FINISH Introduce fine, subtle drawing-paper grain, slight pigment irregularities, delicate graphite buildup, faint smudging, and natural pencil pressure variations. Keep the paper relatively clean and neutral rather than heavily aged or yellowed. The final result should feel like a genuine traditional mixed-media illustration scanned from an artist's sketchbook. Maintain the reference image's raw, expressive, slightly unfinished character while retaining the original photograph's colour richness and visual clarity. 9. STRICT COMPOSITION PRESERVATION Use the uploaded photograph as the only source for the composition. Preserve its original aspect ratio, framing, camera angle, perspective, subject placement, relative object sizes, and background arrangement. Do not crop, zoom, rotate, reposition, add, remove, replace, or rearrange any elements. Do not add text, captions, signatures, borders, or watermarks that are not present in the original photograph. Transfer ONLY the reference image's artistic style to the uploaded photograph. FINAL OUTPUT Create a highly detailed, realistic, hand-drawn graphite-and-charcoal illustration with dense, irregular crosshatching, scratchy pencil strokes, expressive architectural linework, subtle paper grain, and restrained coloured-pencil washes. Match the reference image's sketch texture and artistic character while preserving the uploaded photograph's original colours, with slightly enhanced saturation and NO excessive yellow or sepia tint. The final result should feel naturally coloured, artistically detailed, textured, realistic, and visually faithful to the original photograph.
