My Review...

Not bad....
Add some variation to the movement!!
and add some other person too!! like maybe he will dance together with that person!
Also you can maybe make a different expression on that guy looks

Or make it like a story!! like make him walk the park or another place with this song on!! or you turn the song on with the exact timing (if you want to make it a story) with the story!

Well that's all i have to say!!
