I would worry that a Web Designer has trouble with a cohesive color palette.
I was thinking that the green-background section headers would look better white with color text.
I think Ed nailed it pretty well. Big rounded corners are out of style now (unless it REALLY fits the look and feel of the site). You might suggest just a 2 or 3px border-radius just to take the corner off but not be a huge curve.
It’s a dark page, so the white boxes look a little awkward to me. You might ask to see them with no background, or a shade darker than the page background (around #222222) and white text. Keep the upper SHOP NOW section different, but with a slightly darker-than-white background. Maybe even a much-lighter version of the colors that the color-picker uses, set dynamically.
