1. My favorite medium is my pen sphere. This is because the pen sphere sticks out from all the other spheres from its unique style of shading. Since I used hatching for the shading of the sphere and its background, I really like the way it looks. All the other spheres have the same smooth transitions of color, just with different shades and colors from the different mediums.
2. My least favorite medium is the pencil. This is because everyone knows what pencil looks like and the way its color transitions. This ruins how unique the piece can look, even though there are so many different ways to draw in pencil, that style usually looks as you would expect, unlike the pen and cut out paper styles.
