The theme is very casual and looks very good.
I would increase the size of the banner (It's a bit small I think).
It's good that you don't have many topics to start off with. Although I'm sure a few more wouldn't hurt.
The Icons work well with the theme although I think you could do with better group userbars.
Also I think the navigation bar Icons are slightly to big.
I think it has potential though. Good stuff.
EDIT: Slight problem - I'm constantly signing out?
