King of Rocks - part 1 (sketch, base colors)

After having not been able to touch my tablet in, I believe, a week, I was finally able to start working on a quick composition I thought about a while back, just about an hour ago. This particular one was inspired by Lion King, specifically the scene just before the song, "Circle of Life" starts.
At the moment, this only has the base colors and very little shading for the rocks.
