There's a rather large blank space at the top, occupying significant vertical space. Since vertical space is most precious on all screen orientations, I'd consider cutting it.
The art on the 'visual' page looks very interesting, but clicking on them does nothing. At least make them links to the images themselves. The two with school buses are my favorites. I'd move them to the top to make the best first impression (though this is of course subjective! Place your best works first).
My personal blog! Let me know if you like any of the stuff on it. And what I'm wrong about :)
