This is as far as I'm going with pencils. I think it's a little too far, but since I'm not sure what my next step is going to be, I'm going to go as far as I can with what I know best, the pencil.
There are many options here. Ink, Inkwash, Watercolor, or a mixture of all three, or just leave in pencil and digitally color it. So many options. I think I'm going to experiment on something else first before I do anything to this.
