I like it. Maybe it would have a better header (for the black block, I would try to put a border-top and a border-bottom with same color that the body border).
One question I'm wondering (since I'm making a new web-portfolio for me)
Is it a good idea to do the content loading using javascript? I say it because some people disable it.
And other thing: content is showed height-fixed with scrollbar. There a way to make content div height 'expandible-collapsable', almost automatically, isn't it?
