No thanks to my buddy Derek for pushing me to ink these, I finally did so.
Nothing special on the colors. Just used a custom shaped hard brush with multiply layers for each color. The inks I used a black ink Japanese Pentel calligraphy brush and another Pentel ink brush. I love these pens and rarely use anything else when inking :) Oh, and I used Canson tracing paper when I inked it, cause I know aside from being ink rusty, I tend to screw up the original from time to time. That, and I still can preserve the original.
