It's not at all like the rest of the design here. I'm not a fluffy designer at all but the header has plenty of strong dark areas. Also the dark grey actually doesn't stand out enough.
Why not make it silvery to stand out against the dark bgcolor? Or even red?
Also the little popups about members are cute - and useful - but I'm peering at them trying to make out the text and also yucking at the sludge colour. Makes it look like a member has done a poo mess in the centre of my page! Or more seriously like the design is unfinished - colour indecided yet.
