Cool looking project. Unfortunately my browser (Firefox) is really struggling with scrolling on the overview page... It keeps getting stuck while scrolling past the "powerful engine. Limitless" block of text.
At some point, a slick experience becomes a hindrance when it comes at the cost of load time, and this page blew past that point and then some.
The main culprit looks to be high-res PNGs with transparent backgrounds, which are ~2MB each. If you can get away with lightly compressed JPEGs with the same background colour as the page, you'd shave the majority of this baggage off. Obviously it won't look quite as good, but it's all about balance :) Just my two cents.
