I have drawn every character suggestion you sent (unless they were already in there) as well as all the characters you made me think of by association and random-cartoon-stream-of-consciousness. There were so many great ideas that it actually changed the dimensions of the piece. Today the Characternity is 25% taller, taking it from 1:2 to something closer to 4:5.
Now I just have to fit the pieces together so I can start coloring this new layer! I'm really excited, but it's going to be a hustle to have the color finished in the next six days (my deadline to have prints ready for Comic-Con.) I really appreciate all the love and support you've been showing. It's a great boon to my motivation.
Thank you everyone.
