The design is pretty clean. Normally, I love clean designs -- but this might be just a little too clean. It could use a little bit of jazzing up.
The important data for the front page is the company information. I see it at the bottom of the page -- you might move it to the top. Also, I don't believe that "Web" should be capitalized in that paragraph.
All of your subpages show a big green bar -- but your index page doesn't. That's an odd discontinuity which just "feels" wrong.
