Pretty long opening sequence.
Graphis: They are pretty badly drawn. Or maybe its just the way you animated it that makes it seem bad.
Style: Pretty long opening sequence. Got bored within the first 10 seconds. The whole shading of the head seemed like forever.
Sound: I'm sorry to say, but the music just plain sucks. If this is a serious flash, then the music just ruins the mood.
Shorten the flash if you plan to use it as an opening sequence. Wonder what the real thing is going to be like. Hope it isn't like this flash, though.
