The overall feel is nice and clean. There is just something in two colum layouts I really like. The color scheme is awesome and overall a good implimentation.
However this theme falls flat in my opinion when it comes to the layerd navigation. I am using a wide screen monitor so this may have something to do with it. However I don’t actually see any products above the fold line. I have to scroll to see the products in there categories which is never a good thing. I would try and reduce the amount of white space around that.
