It's good, but it could be better. Here are some tips (for all skinners, not you in particular).
When you recolour something, and you want it green, try colouring it with different shades of green that are pretty similar, but not the same. It gives a very lively effect.
I think this skin could use some more contrast, that's easily done by copying your drawed layer to a greyscale layer, then copy it back to your coloured skin, set the blending mode to overlay and the opacity on 40% - 60%. You'll see how much it improves! :D |
