Since your a graphics board and the skin is the first thing a guest will see and they expect it to be good, ill start from top and work my way down
Firstly, your logo, the sides.. they were just stretched! Make it look more neater by getting rid of all them lines
Your Favicon, i dont understand what the HM thing has got to do with your forums..
Shoutbox could be abit longer
Your board icons are way to small! If you would like some high res really nice transparent looking ones PM me
We can see the Staffzone section but no boards in it, you should hide it :P
Your affilates box should have a <br /> directly above it and you should put the word Affilates in the center and make the background spread across the whole thing ^^ And for future reference: if you get to many affilates, put it in a marquee that slows down when you hover over it
Also your
Contact Us - GFXRebels - Archive is not in the center.
And being a graphics board, you should really edit the skin to make it look custom then remove the link to complete gfx
Good luck!
