It looks nice but im not sure about those little blue sections along the right, i feel they dont fit enough with the other blue shades.
maybe its nit-picky, but I don't like the link attracting users to register. maybe button graphic integrating some of the colors or standing out a little more would be good. I don't know - maybe just ask yourself about your main call to action. Honestly, the site looks really good though. I will agree about the blue on the right side.
I think the login section is out of place..You can also move the logo to the left so you can move the login section to the right place..
