It's OK

A bit simple, a bit short, and in only one color. See my favorite Shuffle 1 ... 2 ... 3 to see how it really should look. The character edges aren't very smooth either, but otherwise it's a nice start! Make something out of it! Keep it up!

This does need a little bit more work.

But it has potential. Change the music, or dance, or maybe something else that is relevant to this flash. Add a couple more songs if a sequel comes along, 2 or 3, it's up to you. Overall entertaining however needs more content to keep it watchable.
