I like a lot how you mix curves with pointy edges. It gives your drawing a very unique touch And also, I just LOVE how you nailed down the Joker's personality without making him look like Heath at all! It's like your own version of the Joker, and it's absolutely AWESOME!
Nicelly done! Congrats! I've saw your Harley Quinn too and found both very awesome made [both on my favorites now ^,,,^] I just wish I could see Harvey done by your hands too... Once again, great job! ^,,,^
