In my free time I like to draw. I am most comfortable with charcoal, for its forgiving nature. It blends and erases easily. I have also explored other materials and have taken classes in acrylic, water color and oil painting. In addition, classes in anatomy help me to better understand proportions of the human body and drawing them from different angles.
I do this purely as a hobby. It's a great counterbalance to the digital life of my day-to-day work. A nice way to slow down time while learning new techniques by hand.
