用于自然手势研究的AI人手生成器

An original adult left hand holding a graphite pencil in a comfortable tripod grip with five distinct fingers, natural nail shapes, relaxed wrist alignment, and visible fingertip pressure, above a blank cream sketchbook on a tidy artist desk, cool daylight from the upper right with delicate cast shadows from each finger, close overhead 4:3 anatomy-reference crop with the full hand and pencil tip visible, clean realistic drawing study without extra fingers, fused anatomy, text, or copied personal identifiers

An authorized lifestyle photo correction preserving the depicted adult's visible face, body, clothing, table, and pose while reconstructing only one partially distorted hand resting beside a notebook, in the unchanged cafe scene with the original cup and background retained, warm side light from the left matched across skin, sleeve, and tabletop contact shadows, medium 4:3 crop with the repaired five-finger hand naturally connected at the existing wrist, restrained photographic restoration focused only on anatomy with no identity change or invented event detail

An original stylized adult character hand shown in a calm open-palm gesture with five readable fingers, clear joint rhythm, consistent palm creases, and a relaxed forearm transition, against a simple muted-blue animation reference board with small blank pose thumbnails, even overhead studio light with soft graphic shadows, centered 4:3 character-design sheet showing palm view and slight three-quarter view, polished animation anatomy study with no extra digits, malformed joints, injury, or photoreal identity
