ah the mental gymnastics people will go through to avoid admitting the animation is weird. first of all, gambeson is thick, but it's worn outside not inside his leggings, why would it affect how he stands? his pants are just normal cloth. also, you're arguing against yourself. you said armor is thick, yet you draw his shoulders near the outside of the armor? anatomically, that's not where his shoulders would end, also the lines don't even connect to his feet, it barely touches the inside of his heel.
again, it's just a morph to illustrate the point, it's not supposed to perfectly illustrate what the new animation should look like.
this is what normal human proportions look like, no big exaggerated stances. and if you're going to go on and on about penises and school boys, my argument to that would be that a career soldier/lord/captain whatever should be secure about their manhood such that they would just have a normal relaxed stance. this character is also resting on his left leg, but draw those lines here and you'll see the difference.
i'm not trying to be a ****, i'm simply trying to say the animaitons could use a little more nuance instead of everything being big and exaggerated
that feel when you're just a normal human being standing around, and not a fantasy comic book superhero doing the tory powerstance irl:
also, here's a picture from an old warband mod called hispania 1200, they modified some of the animations and you'll notice again, standing on left leg,right foot out, yet again the stance is not wide, it's just normal:
