look at my site? need constructive criticism

[jaguar]

break up the interface a bit with borders, the side bar, left bar, next/prev section and item info all kind of blur together, doesn't help navigation.
Reviews should be on the product page. Are individual item pages even needed? There's only one photo on each, section listing is really enough, there's only a sentence about each.
If there are no rings it shouldn't tell me there are a variety in stock.
Native Breeze needs a category icon.
Maybe make the icons icons that are representative of the section rather than item photos, the difference isn't clear.
Reduce the header size, it's wasting far too much screen space.
Get rid of the ugly-as-sin line between the product listings on the sidebar and the new products link.
Search button needs to be a touch wider.
That bottom ad clashes something horrible.

Don't take it the wrong way, it's not bad but you could do better so I'm being honest. If you need help with any of this drop me a pm =)
