The skin isn't bad but it needs some major edits, the background for one thing stands out way too much and makes me feel a little dizzy, the forum list background looks even worse, should just be a dark Grey colour IMO, the logo would be great if it was not for that horrible background again that just doesn't blend in. The navigation bar is another thing, needs a light blue gradient as the nav background.

I would give the skin right now a 5/10, with the edits listed above, 7/10.
