I have tried a few different mediums this year but I must say charcoal is a special one. It has this wonderful capacity of giving you quick results both with putting down mass and line.
Another aspect is the edges that so easily can be made either sharp or diffused. It is versatile and can cover big areas quickly. It has a lot going for itself!
A while back I tried to do a few charcoal portraits and I was into learning how to make portraits. I made a copy of John Singer Sargent who was a true master of this medium. I think I want to do more of these soon!
