not to be rude but it looks too inspired to me which, for a portfolio, is not a good sign. As H2F said, you really need to give potential clients a good impression.

Although thats not the main problem of the design, the main problem i can see is that the links in the main and nav, and some of the text in general, is harder on the eye's than it needs to be. I'd work on making the site a bit easier to read, make it as easy on the eye as you can

Other than that it's not too bad
