great Job! and Nice Style!!
I think you've done a great job here!!..
I would definately suggest not using gradience on the animation, as it causes major slowdown...Actually I had done a Musicplayer in a similair fashion some time ago...Have a look,and hopefully it can give you some ideas for your next Transformation!!
