sometimes a mistake is a good thing

I started this portrait of Johnny Rotten of the Sex Pistols and didnt quite hit the likeness on the sketch. However, I really liked the drawing that I did get. So I decided to move forward and finish the piece anyway. I like the way that sometimes a drawing will start as one thing and end up taking on a life of its own. Even something as simple as a portrait…So there you go.
