>>1615121I made the colors under the brush effect much brighter in the area you mentioned and it indeed looks much better, so good observation. Also fixed a shape of black that wasn't masked properly, that also helped. Fixed the eye on his shoulder too. The coloring is still not close enough to the original but I'm sure that once printed, considering the size of the stick, it'll look fine.
Let me know if there's anything else you'd like altered. Otherwise, I'll upload the project file and printable version for you if you need it.
