I think the colours need to be flashier. At the moment it's lifeless. "Cool", but not something that you'd want to interact with.

Space usage is fairly poor at the moment. Think about what things are useful that you can have around the place, and what can go. For example, if articles are going to be a major feature of the site, have a small section to the side with perhaps the latest 5 articles linked, instead of making the user click "Latest Articles". People may not be initially interested in your articles, but by a topic you covered instead.

If you have no use for that banner space, have the gallery rotating up there instead. Makes things more eye catching.

Also, for the gallery, stick to a scroll-bar style one. When I looked at what you had there with those pictures on top of each other, i thought the layout was broken. When using a well-designed site, one should know where each click will lead them, not guess.

Consider having the shopping cart amount and access in the top right instead of a drop-down.

Search bar could be smaller. No need to be so big.

The address of the site is unnecessary. If people are seeing the site, they know where to go (or where to find out).
