Well - ummm. the design is doable but I would use a fluid approach and extend it across the site. Next - work on the font of the logo. After that - the banners ads seem to take away from the site - too large. Lastly - the new and old forum pics of the poker chip or chips - looks funny. Make it only one chip like the logo.
At the bottom of the page - the icon definitions - Forum contains new posts, Forum Contains no new posts, etc. Those icons are set for a white background. You need to fix those icons to match the page background. Make them transparent backgrounds or match the colors.
