First impression - nice and clean. I don't like the font used in the header though and specially its shadow ( photoshop standard setting).
Im afraid I have to agree here, but the font used in the logo is the clients own, so I couldnt change it im afraid.
As it is oscommerce, it doesn't validate. Much worse indeed is the absence of permalink structures that are search engine friendly. You might consider adding some rewrite rules.
Can you explain this a bit more?
I wonder if the listing of the products is very good, as they are listed one below another, taking up a lot of space, as the images are first and below all other information. Maybe it's better to float the text left, and the image right beside it?
Again, this was a request of the client. Original design had the images at the same level as the product descriptions, however due to the minute nature of some of the products, she felt that a larger image would be better, thus putting them above the descriptions was the only alternative that I could think of! I did explain to her that clicking into the product would allow the user to view a larger image, but this was a non-runnner also. She wanted impact visually at the product list level.
I have to say however, that I can understand her point of view.
Thanks for the feedback ecuador.
