I'm assuming this a sort of multi-purpose theme that could be used for any of the example uses shown in the template? I think it's very nice, it looks well and it shows a lot of work and consideration of possible uses. Only thing I would say about the design is to maybe introduce more left and right padding on the two post items which have a lot of text in them. They seem to be a bit tight to the edges.
While I like the colors, this is something that just doesn't work and nobody shoud ever buy. First off, using many different colors and elements on very small place makes navigating through content a nightmare, that's why many portals or magazines use very simple design, because it's easier for users to find what they're looking for. This is just a mess of a colors. And secondly, what is this template even supposed to be? Is shopping cart often part of magazines? What's with those lines near every movie or album?
Sometimes I can't beleive what some people produce and how they get praised, even though this is deviant art. And again, I'm not talking about graphics, but about lack of functionality, user intuitiveness and usability. Try to focus primarily on that, not on flashy graphics. Users will appreciate content more than colors.
Trust me, I'm not trying to be be harsh when I comment on something that I find bad in a certain way. And if this was at least little bit better, I would definetely wish you good luck with sales. But as it is now, if it's going to make a decent profit, then I'm only sorry for those customers, because they're just buying pretty picture. If you get decent sales, good for you, but that doesn't say anything about quality of the product. If you can, think about my previous post. Design shoud always be about usability first. Content heavy websites need to be simple, otherwise you're probably creating something that'll confuse and discourage users.
One last thing. Be critical about yourself and your work. You might not agree with me, but it's important to hear someone elses perspective, especially when he's more experienced.
