Pretty much the only nitpicky things I can say are that the mon are yellow instead of white and the circles are too small. The blue should be more vibrant, and the grey should be a bright white. And the kosode doesn't have the little dots all over it (but Stan didn't always draw them anyway).
I definitely wouldn't complain if they did a comic repaint, though. If they did, I would hope that instead of the black robe they included his fur cloak and snow boots, a much more iconic and recurring look for the character.
