In my country we don't have winter but during the Xmas season it tends to be so cold. I love the charcoal drawing, it is so nice. The old man with the head warmer and his coat, this shows that it is cold and chilling. I said old man because of his white beards
You are right @tutufaith, he was a man in the middle ages but i let his beard white, that gives the portrait more charisma :))
