Just submitted some VERY EARLY rankings. I need to show the logos to the Managing Partner to get the real rankings, but you are doing great. Keep it up!
Only feedback for now is perhaps make the top of the icon look a bit more like an "n"? Maybe try adding some kind of mark in the top left to show it's an "n"?
(Sorry, wish I had better words to describe it... this is why I am not a designer!)
