There's alot I like about this site so I'll focus on those primarily - I love the fact its responsive so different screens and mobiles can all see it. A big, huge, massive plus for that. I like the simple navigation and white feel to it. Allows the work to speak for itself. Negatives: The cirlces could do with a really gentle inner shadow on them or something so that any white work is still contained and holds the shape of the site - Some of them are lost and floating to freely for me. Also the hover effects, I havent checked but what happens on an ipad or mobile where hover is rendered useless. Does it still provide a different state. I guess so but just wanted to ask.
Also I would bulk up your pag titles. The Homepage should list skills and links such as the logo design, book covers etc. Will help your site alot that. And do it on every page so the search engines can tell what each page is about.
All in all though, I really like it. It breaks away from big header, 3 boxes underneath, 3 more under that etc. And thats to be commended. Makes me wanna change mine haha.
