Not bad, though I do have some crit.
-Relax on some poses. Too many arms thrown up and down and side to side make for a more confusing animation. And it's more work.
-avoid black lines in the background.
-inconsistent sound quality. Make sure all of it is at 'Best' quality!
-Take cues from the music clips when to cut from scene to scene.
Otherwise, great work! I look forward to seeing more!
