I like the new design. It looks smooooooth.
One thing that I noticed is that you should take a look at the way that the shopping cart functions. When a product is added to the cart, the page page appears to refresh, but there is no indication that anything has been placed in the cart. I found myself hitting the Buy button repeatedly while looking for some indication that something was added to the cart. Perhaps you need something in the left sidebar or the header to indicate that products have been added to the cart. Some sort of indicator is needed to let people know that they have added an item to the cart.
