Ursula the Sea Witch

This is my first drawing using Procreate and the Apple Pencil. I wasn't sure how I would like using the stylist but I really love it. The title of this illustration is Ursula the Sea Witch. She is my favorite Queen. (Yes, she was a Queen for like 3 minutes before Eric killed her.)
I also designed the back of the card because I am going to make this a series of 4. I have my Queen of Clubs, I have an idea of who do do for Queen of Hearts ;). Which other Disney villains would you like to see?
