Your site is looking so good. I love the way the products change the color when hover through the products. It's really creative and attract customers. Why don't you put some of your products (such as hot items, best seller,...) on the Hompage to attract customer from the first sight?
Moreover, your menu color on the top of the screen has white color, so I think you'd better choose the slide which has different color to make the menu visible.
If you want to hear more detailed feedback from experts about your website's UX, I suggest you go to this thread.
Hope it helps :)
