Not bad, not very struck on the design or the header/logo.
The design seems very boxy and basic. Basic is good, but you need something else in there that makes basic work... A nice header, logo etc.
The coppermine gallery can easily be themed to white and turquoise colours like your layout and implemented into a page so it looks overall, a simple put together website.
If the banner was changed, maybe a more basic header
http://www.oxygenpowered.com/ just something simple like that with perhaps a logo etc. I think it would look a ton better!
Good luck
