This is very nice. The design is impressive and I don't see anything that would annoy visitors when browsing. The categories are well organized. Very professional
One thing that bothers me is the placement of the logo and the advertisement on the top. I feel as preference that the logo of the site should stand out but from a first glance perspective the advertisement jumps out of me and its kinda confusing. Like the advertisement looks like a banner for your website so it makes it look like I'm on a different site, if that makes sense.
