Victorian Witch

So I've had this idea batting around in my head about a prim and proper witch from England that flies around town and helps people out. Kind of like Kiki's delivery service, but in Victorian times. She'd also have a cat with her that wears a suit. Maybe I'll call him Puss in Suit. The other day I actually got around to sketching some designs for her.






I really want to learn how to digitally paint and then I want to digitally paint one. Any suggestions would be welcome!
