those banners are too big IMO and I think the text in them too large? try not to use a font that is popular, you're using it as an image banner so why not go for a fancier font?
The background is a bit distracting, try for something more simple like diagonal pixel lines (I think you know what i'm on about x.x) it's a tiled thing, not hard =)
I like the navi though, very visible, good thing and perhaps line the wc3 buttons along the bottom in a row?

Sorry for sounding a bit bitchy, i'm doing we design at uni and I like being critical =) It's a helping thing, nothing more =) Good work though
