hey there, very nice blog. I really enjoy the content being a freelance graphic designer myself. I think technically speaking your menu bar should be boxes for each item. For example, rather than having to roll over the actual text of the 'About' link the entire bar that 'About' sits in should act as a link.
very easy to do with a bit of CSS. otherwise the site looks great, the bits of pink were needed to breakup all the white, maybe some of that color can go into your pretty header?
