We don't know everybody's take, nor can we predict it. I'm sure Tim Burton heard 'learn anatomy' a million times, and he still did what he thought he should. Nobody suffers because we tell them avenues in which they could go to become better. If someone here posts something with bad anatomy, I will give them an anatomy crit. If they blatantly disregard this critique, hey, no biggie, obviously they are not interested in good anatomy. I learnt from trying to help them anyway.
'better' is a lot of things, one goes through a list of them, exhausting them, trying to hit on things that they feel matter. The artist takes from this whatever they desire. You're not honor-bound to take the critique that people give you. It doesn't smother your individuality to hear things you disagree with, nor does it do anything but help you to have to critically assess points of view that differ from yours. In thinking 'okay this guy says I need to learn anatomy, but I don't want to for reason x, y, z' you are progressing as an artist and as a person. If you want this to not happen, then I tell it you it never will go away as far as I'm part of pixelation. People here will get thrown at them all the steps in the 'how to become a pixel artist twelve step program' no matter who they are, as they apply to them. If they want to take something from that, good, if not, I'm sure they'll hear various highly personalized individual crits and nitpicks as they go, if they stick around and people start to come to terms with how they seem to want to work.
As to writing home about anatomy, what are you telling me? That because a lot of people are able to draw human anatomy semi-properly, I shouldn't be happy with myself when I manage this as well? And that I shouldn't try to help other people get there if they so desire? As I said before which you didn't comment on, the way I would draw a semi-correct anatomical human and the way another of these million of people you numbered would do it would be significantly different because people with traditional skill do not become clones of each other. Every piece of art is infused with the personality of their creator. Just because a lot of people have climbed a mountain doesn't mean I can take pleasure in my success when I reach the summit for myself, nor will I erect there the same flag that others did. On mine, there will be painted a pretty billy goat.
Plus, a lot of people here are trying to learn pixel art as an applied art medium. They want to get jobs, and make money from it. In this way, they *need* stuff like good anatomy and good color usage to get ahead in this field. Not everybody wants to make pixel art paintings for the sake of it, you know? Some people want to make game art.
