Not keen on the testimonials scroller, it's a bit too quick to change, and the motion is pretty violent. Also, it's cutting off the edge of the testimonial text in Google Chrome.
That said, the main graphic and layout that looks great to me!
A couple of other pointers...
FAQ:
Maybe use bullets instead of bold text on the FAQ's, or alternating grey/white backgrounds to liven up the text there.
Portfolio:
[In Google Chrome] the gap between the text and image tiles seems to be only about 10px. For my liking, it should be about twice that (which it may already be in other browsers).
Services:
The spacing seems a bit off here too:
>space
text
>space
services
>big space (from the longer print design list)
more service
>small space
text
>big space
image panels
not that keen on the small yellow post-it note icons, but that might just be me

.
Hope that helps!
