I guess you must have implemented the changes suggested in this thread because your site appears to be very clean and professional. I totally dig minimalist design so I appreciate the look you are going for. There are just some minor tweaks I think you need to make.
1. Your logo seems just a tad to big...making the whole heading take up a fifth of my screen. I want to look at your pictures, not your header.
2. The centered text on your about page is weird and difficult to read. Increase the font size and make the text aligned left... and while you're at it, try having your headshot aligned to the right of the text. We read from left-to-right, the focus of the about page should be the text, not your headshot.
3. Try adding testimonials from satisfied customers across all of your pages.
Otherwise, you have a very presentable web site and a nice portfolio.
