Sorry for the delay in replying.
Site looks great, one of the best customisations. Will add it to the showcase soon 🙂
Please correct these things
1. Make below nav google ad background to #f6f6f6
2. Site might look even better if you add subtle grey pattern to body background like you added for footer or you can choose from here http://subtlepatterns.com/tag/light/
3. Get rid of the above footer ad. It doesn’t get many clicks. Or use the newly introduced wide ads
4. Try adding this to user CSS. Your choice.
