I really enjoy drawing in perspective. It doesn't require that you are a great artist, only that you have a ruler. I like how precise you can be in making lines and such leading up to a vanishing point.
I enjoy being able to make cool artwork that looks good easily. I liked getting to draw our art classroom. (thats not it) It was cool how the walls and ceiling slowly came into the drawing as you start to draw details. Perspective is definitely my favorite type of art we have learned so far.
