You do nice work. From design to coding, very impressive.
I only have one observation. You have beautiful portfolios at the bottom of many pages. But they are not noticed unless you drag to see them, which is a shame because your clients work is very nice. I realize you probably don't want to have them at the top of the pages, as it wouldn't look as neat and composed as your current layout. But you might consider adding a "Portfolio" link near the top of the pages, and an anchor to the portfolios, so that they are not missed by the casual visitor.
Again, Great Work!
