I've been working on it since 2014. There used to be WAY more characters, but I noticed as time went on, that the newer ones I was drawing, looked better than the old ones. And when I started using shading in my art, I decided to just start from scratch. I updated the art which at the time, had well over a 100 characters. And re-uploaded it with significantly fewer characters, but they were of higher quality, with much better shading etc. I also made sure the size and scale of the characters was much more accurate. I've just reached the 100+ mark again and I still have characters I drew before, to add back in.
