Well as you can see, I decided to go with a background. But I made it a simple sky & ship ropes bg so as not to be too busy. I think it turned out well. A little more pastel than I was originally thinking, but I didn't want to overpower Captain Kitty.
Original will be for sale at the Midwest Furfest Artshow. Prints will also be available.
Done in prismacolor pencil.
EDIT!: Oh Wow. A Daily Dev! Thank you all so much!
