Motion Control needs compatible sources more than a long prompt: a character image and a performance clip. The model needs to see the body and relate the poses.

Use full-body framing for dance and match the photo's crop for gestures.
Choose video or image orientation, noting their different duration limits.
Test a short passage before a long run, inspecting hands, legs and head turns.
No. This workflow needs a recorded performance.
The photo may lack space, or the footage already crops them. Prepare a wider frame.
Kling 3.0 Motion Control can use the photo or video's background. Avoid changing the entire costume and lighting at the same time.
