Your enter/forums page is very good and looks pretty professional.
When you go into the main site however it looks a bit of a mess. Try to use the same colour used on the enter page on the main site and also use that yellow GameZ logo in the top left corner again. I'd take away the current sort of bluey background because it doesn't look very good in the different sections and doesn't stretch all the way down. You could probably do with putting your yellow GameZ on the forum as well rather than Gamez.exofire.net again. Otherwise it's pretty good...
