I like them both, especially the second one! Very cool and sleek.
The first one: the header doesn't line up with the image/rest of the site in ie7. It is only out by a few pixels but enough to notice. In ie6 there is a different problem-a few pixel gap between the header and the image! I see that it is fine in ff though
(sorry! You could check them in browsershots.org and see what I mean)
They do look great though!
