Well done, Kevin!
All right, Firstly: Damn well done.
I can see some of the animations inside the animation (if that makes sense) are made directly from the "originals". You might've used the "onion layer" in flash (That is good practice by the way.) but isn't really original.
However a lot of the sequenses (like how the DJ is moving) are made from the bottom - and boy! How I like that!
You've done a great job lip-syncing - I know it's a pain to lip-sync, so thumps up. The graphics are nicely done, and well syncronised with the music.
You must have the potential to create your own anime characters now, instead of "copying" other already-made characters. That would be eye-candy, if you could create new anime characters with a real story and an anime world.
You have good potential - so keep it up!
Looking forward for your next creation.
