Create one vertically stacked before-and-after comparison using the supplied image as the only sourc — AI image prompt — GPT Image 2.5

Create one vertically stacked before-and-after comparison using the supplied image as the only source. LAYOUT:Exactly two equal-height panels: original image on top, transformed image on bottom. Both panels have the source image's aspect ratio and identical width. The complete canvas is twice the source image's height. Join the panels directly at a clean horizontal seam. No thick divider, extra panel, decorative frame, labels, or added text. TOP PANEL — ORIGINAL:Place the supplied image unchanged in the upper half. Preserve its full composition, original colors, lighting, details, existing text, and crop. Do not redraw, retouch, stylize, or apply texture to this panel. BOTTOM PANEL — OUTSIDER ART:Redraw the same scene as a flat, densely textured naïve folk-art print. Preserve the main subject, recognizable silhouettes, relative positions, important objects, and overall composition. Do not invent additional subjects or props. Flatten the ground into map-like color zones, with people, trees, buildings, and objects shown in simple frontal or side elevation. Remove converging perspective, photographic depth, directional lighting, and cast shadows.Use warm paper white, warm ink black, and two to four subdued colors derived from the source. Choose one existing object or connected detail as the only saturated accent. Give each large zone one consistent handmade texture: stitch marks, irregular window grids, or dense foliage marks. Keep the texture dense, rhythmic, and slightly imperfect. Where people appear, use small, solid, faceless figures with filled clothing and limbs of visible width. Render every surface as opaque printed ink on matte paper, with no photographic remnants.Keep all illustration, paper texture, and color changes strictly inside the lower panel. No gradients, glossy vector finish, watercolor, stick figures, cute cartoon proportions, invented lettering, or watermark.

TOP SECTION — ORIGINAL PHOTOGRAPH: Place the original photograph in the upper 55–60% of the canvas. Keep it photorealistic and naturally detailed.

BOTTOM SECTION — HAND-PAINTED INTERPRETATION: Transform the same exact scene into a delicate minimal watercolor and fine-ink illustration. Recreate the main subject, pose, perspective, key objects, and recognizable background elements from the photograph. Use loose watercolor washes, subtle pencil/ink outlines, imperfect hand-painted edges, soft paper texture, and restrained pastel tones. Keep the illustration airy, elegant, and slightly imperfect rather than digitally polished.

TYPOGRAPHY: Add a short elegant handwritten brush-script phrase underneath or integrated naturally into the illustrated section, similar to a premium lifestyle editorial poster.

Convert this photo into a detailed black-and-white ink illustration of the subject on a plain white — AI image prompt — GPT Image 2.5

Convert this photo into a detailed black-and-white ink illustration of the subject on a plain white background, 3:4 vertical. Redraw the person or people as a hand-inked line drawing — clean confident pen lines, varying line weight, no color anywhere. Keep them full-body and centered, at the same pose, body angle and expression as the photo, with generous white space around them. Keep the likeness. Faces must stay clearly recognizable as the same individuals: same face shape, eyes, nose, mouth, eyebrows, facial hair, hairstyle and glasses. Draw faces with lighter, finer, more restrained linework than the rest of the drawing — just enough line to describe the features, no heavy shading on the skin, no harsh outlines across the face. Describe form with line, not gray tone. Use clean contour lines for edges, and fine parallel hatching only where a fold, shadow or texture needs it. Render dark clothing and dark objects as bold solid black fills, and light clothing as white with only its seams, folds, pleats and stitching drawn in. The contrast between solid black garments and open white ones is what gives the drawing its punch. Keep every detail of the outfit and anything held or carried: patterns and prints on fabric, batik or lace texture, stripes, bag straps, watches, jewelry, earphone cables, shoes with their laces and soles. If the clothing has a printed graphic or logo, redraw that artwork as line illustration inside the garment rather than leaving it blank. If the subject is seated on or using an object — a chair, a bicycle, a pedicab — draw that object in full detail too, including spokes, frames and mechanical parts. Delete the entire background. Pure white, empty, with nothing drawn behind the subject. The only grounding is a loose scribble of short horizontal pen strokes forming a soft shadow directly beneath the feet or wheels, fading out at the edges. The finish should look like a skilled artist's ink portrait — crisp, graphic and confident, with clean edges and no smudging. Avoid: color, gray airbrushed shading, soft gradients, pencil smudging, a photographic or partly photographic subject, a changed face or identity, a generic or idealized face, a cartoon or anime style, chibi proportions, heavy outlines across facial features, a background of any kind, scenery, buildings, a frame or border, cropped limbs, altered pose, altered clothing, missing printed graphics, text, signature, watermark.
