looks good. It seems that your "home" and your "about us" is a little flip flopped when it comes to some information.
I would look over that a little more and FIRST make your about us page focusing on what "about us" really is. And then on the home page provide maybe even some of the same information but either in a different manor or exclude stuff altogether so that your home page is concise and doesn't ramble on.
Not that your home page rambles on to much right now though I just think it is a bit confusing with basically to pages that are doing the same job. You need to make each page have a focus on what information you want to be providing.
Good work though, it is looking really nice. (thanks for the link to TGS )
