Identity (always use with the uploaded photo)
Use the uploaded photo as the mandatory identity reference. Keep 100% of the original characteristics of the person: same face, bone structure, proportions, apparent age, gender, ethnicity, skin tone and texture, eye shape, nose, lips, eyebrows, hair (color, volume and hairline), and overall body shape. Do not alter or reinterpret the face, do not make the person younger or slimmer, do not change any facial traits or remove real imperfections; only apply the architectural sketch style described below while fully preserving the identity from the uploaded photo.
Positive prompt – expressive architectural sketch portrait
Transform the photo into an expressive architectural sketch portrait. Use dynamic ink‑style linework with varied line weights, as if drawn with technical pens and markers: thicker contour lines for the main silhouette, medium lines for facial features and clothing edges, and finer lines for interior detail and texture. Add loose perspective guidelines, construction lines and quick diagrammatic marks around the subject to reinforce an architectural, conceptual‑sketch feeling.
Use hatching and cross‑hatching for shading on the face, hair and clothing, following the form to suggest volume. Behind and slightly overlapping the subject, apply free watercolor‑like washes of muted colors such as soft browns, cool blues and gentle oranges, in irregular patches and gradients, like an architectural watercolor rendering. Keep the background mostly light and abstract, with these washes acting as atmospheric blocks rather than detailed scenery.
Overall, maintain a hand‑drawn concept design studio aesthetic: energetic strokes, slight line wobble, visible pen pressure, and a mix of precise technical lines with loose, gestural marks. The final result should look like a professional architectural sketch with artistic marker and wash touches, modern and expressive, as if taken from an architect’s presentation board.
Negative prompt
No photorealistic rendering, no smooth airbrush shading, no 3D look.
Do not use heavy solid fills or flat vector shapes; shading must come mainly from linework and loose washes.
Avoid cartoon/anime style, rigid comic inking or thick outlines only; keep it architectural and conceptual.
No busy detailed background or realistic environment; keep background abstract, with only soft washes and a few construction lines.
