Right, so I made a portrait of Koishi Komeiji from Touhou ~ Subterranean Animism, but I don’t quite know if I should improve (or fix any major blunder) on it before passing it off as a submission.
This is the color-adjusted portrait, it works, I think.

This one is the scuffed original work I had to reduce the color of.

By all means tell me knowledge, I crave improvement.
