A little too dark, in my opinion. It's hard to tell where one board starts and one ends because they're pure black. Maybe a nice gradient here would fix this. Also, the red font used to show latest posts, just not feeling it against the black.

Sexiest vB theme I've experienced is that of http://sportgfx.com - it's custom designed though. Also, if you're keen on the really dark themes, hit up http://hackertalk.com - nice, but once again custom built.
