this is really cool. it allows me to see the "tools " needed, and the process involved in your work. i am curious, what kind of paint is that? is paper better than canvas? i want to go outside when the weather breaks, and paint ( but i dont know how how, i can only see visions in my head. am lacking techo knowledge. do you just freeform the person from your head, or do you use a pic or live person etc? is that charcoal? is it erasable?
