I found a hobby in Art towards the later part of high school where I enjoyed drawing. I enjoy drawing because of the different types of shading you can get with just one colour. This is the reason this website using many different shades of gray. I found that one of my most enjoyable projects was inspired by Max Ernst's impression paintings.
