Looks good, well structured, intuitive and easy to navigate.
Only suggestions i'd have at this point:
- darken the backdrop a little more.
the yellow in the header, followed by a very light shading of gray doesn't work. It would almost be better to gray scale it down a bit more and offset the listings with a bit of a drop shadow or give them some depth perception by other means.
this is, of course, purely my personal taste, but i think it would improve your overall presentation.
