One thing I think may help you out is to spend a bit more time editing your copy. I've noticed that a lot of the wording comes off awkwardly to me (I'm a native English speaker), and I'm guessing that with better copy you'd generate a lot more sales.
Also: the new site seems a bit wordy. For instance, half-way down the page I'm greeted in big letters by the sentence: "Welcome we hope you like our themes".
Since at this point I've already familiarized myself with the content of the site, seeing the 'welcome' message there seems odd, and draws my attention away from the themes.
Lastly, you should have more screenshots of the themes. I found myself really having to look closely at my monitor to see what the themes actually looked like, since I couldn't find a way to make them larger.
Anyhow, best of luck with your new project.
I believe with comments like these people like Patrick can continue torwards their goals.
