It is rather dull needs alot better background, the banners will probaly take visitors away from your site which you don't want. You also need to include alot more content such as why your traffic exchange is unique even if it isn't, sell it more and include a main theme running through it associated with your domain name. Besides that it looks like you are on the right track.
The site is too plain.. there's no actual "layout" design. Also, for your white links bar, the contrast is too stronge besides the black background... try using a dark-ish grey instead.
