Really nice.

I agree some clearer / easier-to-find contact options wouldn't go amiss.

The 'Blog' link at the top is a) a little hard to see and b) doesn't go to a blog (just reloads the homepage).

The little 'Ai' and 'Ps' icons have that magnifying effect enabled, but don't do anything special when clicked. Same with the picture on the Welcome slide.

All good apart from that. Really nice design and implementation, valid xHTML. I likes it.
