I tried something different on this coloring. I tried to get rid of most of the lines to make it look more realistic. I also tried not to make the colors too light, keeping the brightest areas of the skin as true to the natural color without changing it. I also kept the original art rather than tracing it with ink. I like the essence of the original art.
The original pencils are done by Paolo Pantalena
