This is great! The colors look so rich and lively. I must agree with you about being uncomfortable with color. Most of my drawings are purely in pencil and I think that gives me a better control to the shading and blending. Since I have little experience, I struggle a lot with coloring and trying to make them smooth and nice.

However, just like you, all my last drawings have been full of color as a way to overcome my limits. Even when I still have a long way to go, I'm starting to feel better day by day. We have, as you said, to challenge ourselves.
