I went in and quickly looked over every one in detail. I chose only a few that appeared to be definitely, obviously, and logically better than the rest (atleast to me anyway). Those are:
My condolences to Arrianna and Chief. You two had good ones, but they weren't my taste.
Out of those 4 which I chose, it was hard to narrow it down. I'm putting Flawedmind at 4th. Sasurai takes 3rd. Reese was one of my personal favorites, and I loved the font used, but no one can beat Skillzpay. He takes the banner contest by storm. His Kon banner is ftw!
Seriously though. Every one of Skillz's characters are nicely placed and all have something interesting about them. Great choices, in my opinion. I also like the fact that his logos actually match the skin. Also, while there is a consistent style, there is a different background on every one of skillzpay's logos that keep it nice and fresh. Seriously, he has the best logo here. Come on, folks.
Good luck to all regardless. Vote Kon!
