One of the things I enjoy about using charcoal is the sense of moodiness you can create with it. Maybe it's just me though, but it seems with paint I tend towards bright, colorful and sunny whereas with charcoal I tend more towards dark and moody, the medium just lends itself to that. Here's my latest example;
"Landscape Study I"
10" X 14" charcoal on paper
I did this charcoal drawing as a study for a painting, one that I've already started and guess what, it's turning out sunny and colorful, oh well, I gotta be me.
