I like drawing visual art on paper.
I like to draw visual art, but I am not good at it. 
You should try drawing with pastels or wax colored pencils. These will make your drawing stand out more. What kind of canvas do you usually use to draw?
Usually just regular old computer paper. Do you know what the best paper is to use pastels?
I like to use cardboard instead of paper when using pastels.
Do you draw professionally or just for fun?
Just for fun, as a means of public expression.
Have you ever sold your work?
Yes, but not my freehand drawings because they are usually just unfinished sketches.
Well, it's a good way to make some extra money.
