Well, it looks like the content is more in function of the design instead of the other way around, the background draws too much attention and takes more space than the content itself. Aside from that the animations are well done. Some of the wallpapers have anime characters that haven't been cut out very smoothly, although I like the light-effects of the logo's. I wondered: have you made the water-drop yourself? If so, with 3D max? I assume it's a liquids plugin if you have. (You should cut down on the light-flares though)
What I think ^_^
