This looks interesting, but I'm thrilled to hear that you are actually talking to customers first. Listen to them.

Nits: 1) I don't like that the 3 sellings points on the splash screen are aligned with 3 unrelated feature images. I was expecting each image to reflect each selling point and got a little confused.

2) The green hills footer bugs the crap out of me on the inner screens. Seeing text peak around a curved footer when I'm scrolling just doesn't look right.
