I think the site looks very promising, but at the same time it feels unfinished. It seems like a excellent layout that you just need to tweak around with a while to get the result you're looking for, if you know what I mean. That aside I think the biggest problem the design has is the lack of color and contrast. While the reds provide a neat focus, I think additional lightning could work wonders along with more highlighting of key elements (buttons mainly). You should try adding a semi-transparent (because of the existing header objects) header image / graphics, I think that could help with the tone. Hope that helps.
