Your site looks good. I like the colors. I have a new site as well and feedback is important. Good luck!
I personally dont like the google ads in the middle of your sales items. You main source of income will the sales, not ads.
I don't like the fact the the google ads are all over the page, left, bottom and middle. I suggest keep them all on the left, the middle once are very distracting.
It's like those mini-site flooded with ebay stuffs. It's alrite. But if you want higher conversion, you should remove the ads and let your visitors to focus on the Ebay item only.
