If you've got an original characters you'd like to see drawn, reply with a description including physical details, attire, background and personality. If you have a visual reference sheet, great, provide that too.

If I've drawn one or your characters in the past, please sit this one out

I do this to help develop my character design skill and to work on something not mainstream, and it's just nice to give someone the opportunity to get their character drawn by someone else (in this case, me).
