The design is not bad but I think if you changed the color of the links in the navigation of the site to black that would make it standout a bit more.
Looks ok. Use background on left links, right images are fluid and seem to be set to float right - this causes some problems in browsers using large pixel sizes and it breaks up the continuity of the page and leaves a huge white area in the middle of the page.
I saw your website in another post you made, I think you should add something where customers can review the product.
