Begin with the supplied original open-hand drawing, palm facing the viewer, thumb on picture left, coral cuff and teal forearm below. Keep the camera fixed. Turn the same hand and forearm slowly around the forearm’s length so the palm becomes narrow in an edge-on view and then the back of the hand faces the viewer. Let the thumb travel continuously around the hand outline; do not mirror the image or teleport it to the other edge. Palm creases become hidden as the palm turns away. Keep all digits part of the same hand and keep the wrist connected to the turning cuff and forearm. Stop in the back-facing pose. No second hand, object, wave, finger curl, cut, extra digit or detached wrist. This is an untested surface-continuity request.
