Yes MintheTea, that sounds like a good plan!
The character creation that we've seen on the art board is coming along so well, so I'm so glad you're not going to give up!
Most of the authors I've known have started out with short stories before they moved on to longer works. The quicker payoff of finishing a short work reinforces the habits (and discipline) needed to stick with that same process for a longer period of time.
Personally, I'm really looking forward to seeing some environment/setting art, when you get around to it!
