First flash? Wow!
_Good Points_
For your first flash this was extremely good. The synching of animation to the music was also very good and as for the fbf, you seem to have mastered the basics. The song seemed to have fitted the animation (even though I hated the song - but that's just my taste of music don't worry about it. And I'm not bringing down the mark on music because of that.)
_Bad Points_
Sorry to say but I didn't like the character too much, the colours were pretty horrible. You used the same movie clip over and over which made it repetative and slightly boring to watch (even though the movie clip you made was really good.) Could have added more detail in general really.
_Overall_
For your first animation it was fantastic! I'd love to see you make a animated story I think you could pull that off fantastically as you do have a lot of talent. Nice one.
