I really liked the sketch of this picture. I got very inspired the more I looked at it, so I decided to do this grand master plan I had in my head; Lineless art with a "Gotham City"-ish background. Not bad for a first time with lineless art!
Also I just HAD to make things even more Harley Quinn by having the bat signal replaced with her own "Harley Kahn" signal. Like I said, I got inspired :D
