I love how portable copic markers are. For these drawings, I printed copies of my line art and took them on the road with me. I wound up coloring one on an airplane and the other at a library. I felt like a kid with a coloring book and a box of crayons! It was fun and relaxing.
I like having copies of the line art in case I want to try different color combinations, and also to try out different opacities for the lines. Howl and Sophie's lines were reduced to 60% opacity. Doesn't it kind of look like pencil? I like how soft it came out.
