Its good, thanks for colouring, maybe a little more shadow/light in some parts, and the skin color is the only thing I can add, hope you keep with the colouring, maybe another doujin from this artist., keep it up.
Base +6, scentedcollector +9, Raiya95 -7, denisimo2253 +5
It turned out very well! If I can find any flaw, it would be in the color of the skin. I hope you continue coloring, if possible you could color the continuation of this doujin.
My only complains would be that the mid tones of the ink dont mix well with your flats and having the same tone in the background washes the intensity of the scenes.
