What happened with the theme?
I think it looks quite nice.
One part you should think about I think, is the readability on your texts. Some parts are quite hard to read.
Seems like you are having too many categories in the top menu.
Otherwise, ask the author for help
Well, its a good start but I think you have a lot of work to do before its ready for ThemeForest.
First of all, the responsive features doesnt work 100%, some elements overlaps in smaller screens.
In terms of the design, I think you should work on alignment. Try using a grid system and make all elements placed in a natural flow. Please see this screen for an example. http://openthemer.com/fluzz.png
You also need to work on typography and visual hierarchy. Its hard to see headings, or which parts of the content that is most important.
Work on that, and maybe put some more energy on details, like borders, icons, buttons etc, and this will be a nice theme:)
Well, font-face and directly importing from google looks pretty much the same on windows I guess. I haven’t seen any difference. Maybe some fonts looks better in certain sizes etc which makes google fonts render perfectly in wondows.
If you want a bit more smooth rendering you would try using cufon. (It may too smooth in some cases) If you can not mark the text letter by letter in a website, it probably use cufon for rendering the fonts.
