8D Awesome. I want to too, because I've done some Traditional stuff recently(I havent done any in a while) But I want to colour them and I have to wait Lol, well it will be worth the wait ^W^ I can't wait to see what you colour next 8D!
If your new I can help you out. To do commissions you can either advertise it in a journal or go to people's sites and offer and art trade. Get yourself out there and noticed because you have some real talent.
When I do commissions I don't charge people. I don't beleive in charging for my art because I don't think I am good enough to do that. SO what I do is do free commissions and that helps me gain watchers and some fanart of my own characters sometimes. As for paypal, I know the basics on how it works but not enough to help someone out with it.
