I like the bottom half of it a lot, the header is what would need some work. The font choice for the header text isn't the best - that is, if you are aiming for the web 2.0 look through-out. That's not to say that it looks bad particularly, it just looks slightly different style to the rest of the page.
Is the project definitely gone or can you submit more designs to him? I'm sure with people's advice in here you'll be able to come up with something a little more appealing
