hey dpixel so i took some details from your version and fixed places where some delineation could help. i noticed that your version seems more feminine somehow. i compared the body structure between the two images though, and they were exactly the same! crazy how just the shape of the head & face can do that. i tweaked my face but it still doesn't appear as feminine. next i might try making it more like yours.
also even more color reduction. definitely helps with definition and crispness.
i did bring back the slightly brighter, slightly duller flesh tone used in the original for highlights. it adds something, i think.
i wanted to point out this thing about color to people, you see in front of the neutral gray of the forums she does seem to get lost but in front of the intended background colors, which are quite bright, she stands out a lot more.
