Helm:
I remember you - if it is the same Helm. Really love your work. Thanks for the welcome.
You're anatomy knowledge is much more adept than mine (mine is actually pretty bad) I'm going to defend some things on my comp:
AA - It is simply because I have to pull off a entire mock "game" by the end of this month which is why I am foregoing intense AAing, and also adapted the style of black outlines for all the sprites (for simplicity and ease of animation, but something that I've never really done before as I usually color my outlines), so far the assets for the game are a little more intense than the Scott Pilgrim game in keeping black lines. The only things which lightens the black lines will be the additive glows added "in-game" -- in fact I might have to give up on the pixel flares I added on the poster and go with... not 8/16-bit ones, to build that atmosphere without pulling out my hair.
Jawline - I agree the anatomy is a bit in want, it does feel a bit cheated. While it can still be fixed, I do want to keep some sort of darker shadow there (thick Tron legacy poster) rather than a rounded chin. In fact the edit you made was closer to what I had at first, but I felt it wasn't dramatic enough. Perhaps my current result may not be a very good solution...
Tube legs - I do love the way you defined it, however again like you said, I am going for that more slender look -- the new legs are too Western if the girl is Asian, and her thighs end up too close together at the top which may be anatomically more correct but, makes her a bit more chub chub than I wanted.
Cyangmou:
On the portrait shot, her head is a bit big for her body haha I need to fix that. Her boobs were moved an inch down already in this one, I'll show you the original which is eve more off. I think the comparison is a bit dramatic though, but I understand what you mean. She is also looking upward in the smaller version. I also have a super deformed in game character (which I made before the portrait, which is why as a reference the portrait ended up with too big a head) -- so I am not sure about super consistent proportions.
If I have time, I will animate the portrait (3-5 frame loop). The girl anatomy is even more off (this was the original, her body is too small/boobs are too high). With the AA issue on the lines in poster... well the hands on the mask guy is going to make you cringe.
