Great job on it! I agree with Eirik in that the beige doesn't seem to fit in very well however the grey and green look great together. The only other thing is that the soccer ball lock/new post/etc. icon seems a bit large in comparison to the other things (in the forum listing) and a bit too small in the post reply button and the header (just the text part) could be improved on a bit in my opinion.

Looks amazing overall though, keep it up!
