When building websites with a "fixed look", use "fixed tables". When I have my browser full screen, there are huge blue bars on both sides of the layout. Plus, I would think of using a more professional design. There are loads of logo sites out there, and presentation plays a big factor. Afterall, you're trying to show off your creativity. As it is right now, the site looks unprofessional.
I would also get some better logo's in your portfolio. Also, the same samples appear for the $15.00, and $29.00 logo's.
