Hi,
From screen shot, your front page looks good. Based on your description the following questions come to mind:
-Who’s it for? Who’s the target user for this specific theme? The more exact you can get, the better, especially if it’s an under-served market.
-What’s the drag and drop page builder you’re using? A premium plugin, or something custom?
-What are the “goodies” for this theme? ie what can it do straight out of the box to get a website up and running?
Not really technical data here (but I don’t have the info for a technical review), but branding is as important as anything. What “Top 10 WordPress Themes for xxxxxxx” list does your theme belong on?
Hope this helps.
