Coloring this one was an experience. I was back home this weekend, but I forgot to bring my art supplies with me so I had to make do with what I had left in my room.
This did not include markers with much ink left in them or a pencil sharpener. After about an hour of basically using my markers as solid watercolor sticks and sharpening my colored pencils with an exacto knife, I finished the coloring on this. Hooray.
Markers, colored pencil, sharpie.
