Here's a couple of minor things I suggest:
1) On the portfolio page when a user clicks on "Visit this Project", I would have it open up in a new tab. Why? Because, it takes people completely away from your website and if I want to get back to it (so, I can continue to learn about your skills) I need to either retype in your URL or hit the back button a number of times.
2) On your home page under "Recent Work" when a user mouses over each photo another box comes up and when the user clicks on the box it takes them to the top of your portfolio page. Taking users to the top of the portfolio page is a bit confusing. When I clicked on the box I expected it to either take me to a page dedicated to describing the project or to the projects website itself in a new tab. So, when I was taken to the top of your portfolio page I didn't immediately know where I was suppose to go next.
3) I find the background distracts to much from trying to read your website. but, that is just me.
