Very Splendid!
Excellent Animation! A few critiques though:
- A play button at the front would be nicer than just starting
- The ending is abrupt and we're left with a black screen; it could end better
- The background moves past faster than the figure appears to be running. You cold fix this by incorporating a midground AND a background. The midground moving faster than your background, of course.
Good job. Your animation skills are elite.
