Yup, I don't do often because I just don't think about. When I played judo I hurt a lot my right arm/hand/shoulder, so like I took the habit to play more with my left side, I did the same at drawing. The first time I had pain for six months, I could go crazy without drawing.
As I said, I was trying to draw Lucifer with my main hand but I broke a glass. By the way that was not the first time I drew Lucifer/demon themed drawing with the left hand, they're in my notebooks. In the past left-handed people were considered cursed by devil, so there is my fixation.
