Here are two websites I think are awesome:
This channel is filled with step-by-step drawing tutorials. If you decide to draw one, put it in the museum so we can all check it out.
This channel is by an artist named Mark Kistler. I used to watch him on PBS when I was a kid. He used to have a show called "Commander Mark". If you look under the videos section he's got a ton of step-by-step drawings. Post your drawings in the museum if you decide to draw one.
