Chris,
It looks good. I don't know web design, but I know what appeals to me as design. It kept me looking which I suppose is the major key in having a successful website. Whether it was the color combination, or the text size/color or general layout, it kept me there.
The "About" page (for me) is too much text. My action was, I read the About paragraphs then I didn't see an end to the text, so I scrolled. My instant thought was "I don't want to read all that". I actually did, because I do like your work, but I tried to be unbiased and I have a bad feeling some people will feel the same. The problem is, the whole page is worth reading to fully discover what you are offering, and it would bother me that people will bail way too early.
I think your "Contact" should be at the end of your navigation bar, because if I want your services for commerciaL reasons, I want to flow from your introduction, to let's see some examples, to, let's get a hold of this guy.
If you have approval, footnote the bottom of your images. This will (at minimum), display prestige. e.g. I saw an image of a Sheraton Lobby, with a footnote, your potential customer's reaction will be, "huh, he's done work with reputable companies", kind of mentality.
If this was my site, I would be very happy that I have something to work with. Good job.
