Poz ve ışık analizi

Convert the figure into an artist's pose-and-light analysis sheet, not a finished illustration. If a reference image is uploaded, use it as the strict anchor for pose, body tilt, weight distribution, camera angle, and the implied lighting situation; otherwise construct the pose described in the user request. Draw a single rough mannequin-style human figure in white sketch lines on a pure black background: white body contours, visible internal construction lines, joint and flow guides, and a simple featureless mannequin head with no face, hair, clothing, accessories, or personal identity. Preserve silhouette flow, head tilt, torso and pelvis direction, and limb placement so the pose reads instantly. Then visualize the inferred light sources as green glow only, with clear intensity variation — electric green at direct strikes, calmer emerald across turning planes, and a faint green veil for reflected spill and distance — mapped onto body planes such as the skull, shoulders, chest, pelvis edge, thighs, and floor contact points. Mark only plausible illumination with short arrow labels identifying the key source, edge separation, ambient support, or ground reflection; never invent random lights. No scenery, props, rendered anatomy beautification, finished character art, or polished illustration finish. User request: a runner mid-stride lit from the upper left
