While, there often are a lot of designs on Behance, this redesign looks pretty well thought out. It's often difficult to create things that are both visually interesting and easy to read — it seems the designer has been able to accomplish that here.
You can't possible tell if it's going to work well or how well thought out it is without a real experience in a browser. At this point, it's just nice pictures. Nothing more. Might generate some design leads though (which is the only reason why this exists I guess).
