Begin from the supplied original crossed-arm adult illustration. The coral arm starts at the shoulder on picture left and its forearm is in front at the crossing. The teal arm starts at the shoulder on picture right and passes behind it. Keep each shoulder, elbow and wrist connected to its original arm. First move the coral forearm outward enough to clear the overlap. Then let the teal forearm open, with no arm passing through the other. Lower both arms into a relaxed separated position beside the same torso and stop. Keep the body facing forward, the camera fixed and both elbows and wrists visible. No clap, object exchange, sleeve-color swap, extra arm, fused wrist, costume change, cut or recrossing. Preserve the illustrated style; this is an untested continuity brief.
