I'd suggest an intro from the about page to be before (or above) the first portfolio image.
Also making the images links to the 'view more' section.
As much as I like elements that are different, I think that a normal vertical style page scrolling would be better. Just because it's not working too well on my mouse, it's moving too fast (which could be my settings). If a potential client feels the same it could lose you business?
A bit more colour in the site maybe? Like the ones used on your flyer?
Lastly, just use a slightly bigger font. I remember reading somewhere that "only designers like small fonts" and that has stuck with me.
That's only my 2p, it's not meant to sound harsh, just another perspective.
Good luck.
