It's a good try, but I think the filler font is too close to really read, esspecially by those with bad eyes like me.
I'd also say get rid of the forum-like things like register, their login with messages, etc. because it's a portfolio site they are not needed to exist.
Add some snazziness to the headings too they don't stand out really well against the body text.
(Will add more later)
(And thanks for not flipping out stupdily like BoxWood)
