the top is really good, but as i was looking at the bottom the design started getting sloppy.
`the buttons don't really tie in
`the footer looks bland and boring
`I do like the arrows
`I wish the text was a bit bigger, you have a lot of room to work with
`I have to disagree with cyclop, Im not really against the navigation, although I don't think that the "Sign up | Login | Help" header really fits in, just like the footer
this page makes a really good splash page, but have you considered how you are going to place content once they go into the site? that's one thing I find difficult after building a splash page.
