your opinions on a header...

For some reason, I'm literally "seeing" the site title last in both of the samples. I'd try a different font or give that one a different treatment. I also agree the background table should have some texture added to it to help give it depth and pull the pics up a bit. I'd also take the big fella on the right and do a slight "darken" and up the contrast on it a little to give him a more ebony coloring and sheen.

I don't think it need to be overhauled. The second does look better, but I would make the title a little smaller because it makes the images behind it look insignificant. Bec's idea of darkening the guy on the right is great and maybe you can have the background gradient lightened a bit. That should make the title and images pop a little bit more.
