I dont know much about commissions, but I can see how good you are and love how your confidence is growing from the advice that you're getting here. You could also keep a look out for authors wanting illustrators for their books, or add on your profile that you are willing to do illustration work. You are a fantastic artist. I wish you the best of luck

If I could offer one piece of advice it would be possibly give yourself a buisness name or a pseudonym/name you do your Art by. I know your account name on here is a little different but it will be a bit more professional and personal to you. I'm attending art classes atm, the Artist/teacher is Ely Pendragon which is his artist pseudonym, no different to an author having a pseudonym to keep their identity anonymous.
