Your page is really attractive to my eyes, but there's two little things that could improve your page dramatically.
First of all, change that text under the Hypermart banner, when you hide it the way it is-it makes it look like you're trying to hide something (maybe you don't want people to know you use Hypermart?) and a way to improve it is to just make it a light shade of gray, close to white, and shrink the size down to about 8 points, it won't make much of a difference in design or respect that people have for your site.
Second, the logo's background doesn't match up with the background of the page in 24-bit color, I'm not sure if it was designed in a different resolution, but I just thought you should know that.
