Overall I think it looks great.

I would change the item names in your catalog display so they are left-justified instead of centered. This is just my personal taste.

I really like the red/orange color theme of the header and footer.

I would work on the catalog background colors a little though (and the side bar bg colors). I think there is too much gray. Try to use soemthing that matches the site more and is more lively, but not distracting. Just my .02

Nice job though
