Looks very promising! However the design to me is a little too tiny, which gives it an amateuristic look.
You may also give it a little more color, I've personally always liked working with yellow/orange boxes such as www.ie7beta.com.
Rather than just saying you don't like it, why not share some of you thoughts on how I can improve it?
They are just reference images for me, kinda like target images.
Add more light colors into it. Look at gmail's interface (although ugly) they have very "easy on the eyes" colors. So basically, add more color... There is more, but I am a bit busy to type it all out. Good luck.
