I was trained to do pencil sketching since 4th grade, and I stopped going to classes after the end of the 8th grade. No one has never taught me how to deal with charcoal, but I just love it since the first try. I did a crappy job in pencil sketching, though..really~lol
I see I am a self-taught too I have started drawing with pencils and I still love drawing them. I tried charcoal a few times but I didn't like it so much. Everyone has their own tools which like the most.
