{"prompt":"Use case: precise-object-edit and identity-preserve. Image 1 is the PAINTED EDIT TARGET. Image 2 is ONLY a geometric likeness reference for the already selected same fictional adult humanoid, NOT a style or texture reference. Keep image 1 unmistakably a painterly science-fiction illustration. Preserve image 1 composition, charcoal shirt, two chest pockets, stand collar/zipper, rolled sleeves, two complete five-digit metal hands, bent-elbow waist pose, grey painted backdrop and face/metal brushwork. Never turn it into a photograph. Preserve moderate stylization, finished face and looser periphery.\n\nMake ONLY localized fine-design corrections:\n- Replace image 1 raised metallic eyebrow strips with FINE FLUSH ENGRAVED mechanical brow lines, not hair and not bulky bars. Fine etched lash edges instead of natural lash hairs.\n- Keep recognizable blue-grey eyes, add a few subtle silver radial/ring iris-circuit marks painted with precise short strokes. No glowing eyeballs or external eye graphics.\n- Preserve exposed symmetrical interlocking crown panels, but give the overall crown outline modest angular facets, not a round dome; do not add a crest or ornament.\n- Preserve natural-shaped ears with small mechanical base hinges, no earring/stud ornaments.\n- Restore only a restrained painted suggestion of the shirt ripstop grid in a few lit fabric planes; keep the folds and broad brushwork, not a hyper-detailed photographic fabric texture.\n- Within the existing head silhouette, keep face proportions/recognizable likeness consistent with the adult in image 2; retain image 1 neutral expression and pose. Do not copy photograph texture. No freckles; keep painted skin planes with restrained pore accents and slight tonal variation, no beauty smoothing.\n\nPAINTING INVARIANT: visible medium expressive brushwork and grouped value planes across FACE, CROWN, NECK, HANDS and shirt; short crisp metal highlights, layered shadow brushwork, mostly soft edges with sharp focal accents, no explicit outlines, no canvas weave, subtle paint relief, diagonal flow toward face. Neutral light-beige synthetic skin, silver/copper/charcoal palette, tiny dim cyan temple dabs. Soft daylight from front-left (camera viewpoint), balanced middle values. Full-bleed approximately 2:3 frame, both hands intact. No signature, text, logo, jewelry, props or extra figures. Gender identity unspecified; no demographic assignment. One fully clothed nonsexual adult avatar.","image_urls":["https://v3b.fal.media/files/b/0aab6f04/NoS5Qmw0Z-SRNP-8mSwMn_rDmDa7bC.png","https://v3b.fal.media/files/b/0aab6f3d/1DEv4mYQO-GKIZ1xEq1wr_uQWClcjn.png"],"aspect_ratio":"2:3","resolution":"1K","num_images":1,"output_format":"png","limit_generations":true,"enable_web_search":false}
