This is a sketch of possibly my favourite character to draw, the Joker. It was drawn for Club Batman ( [link] ), who you can check out here, as they are celebrating their 20th anniversary.
Only recently have I changed my approach to how I sketch my Joker. I've decided to play up his creepiness more, which I think makes him more dangerous and utterly sinister. Initially I was worried that I had made him utterly terrifying, as though he spent several years living in the worlds of the Se7en and Saw films. Judge for yourselves, lol.
Many other artists have contributed pieces, to commemorate the momentous occasion, so by all means go and check it out for yourself.
