The new Cpose stances.

[Roda]

Idk, I can turn my wrist like that no problem...
And I love the new pose, it looks so sassy! I've been wanting it ever since I saw yshtola use it in arr.

I find the one hand one weird. Your hand is just floating there, and I know it's to accommodate clothing , but it looks like you're telling the doctor "It hurts right about here."

[Halivel]

I just did it and it's kind of okay? Not the pose I would stand in for long, mind me, but it's not that bad. Not when you carry sword of your own body size.

It seems okay to me. Unless you have severe mobility issues with your wrists, you should easily be able to hold your arms like that—whether or not it would be particularly comfortable over a long period of time is another matter.

Maybe it’s also a cultural thing, because it’s a common pose in Japanese media when a character is annoyed or being sassy when they’re confronting someone.

The one I have a problem with is the one-hand-on-hip pose because you’re doing a weird hover hand thing to avoid clipping.

The one pose where the hand is just floating by your side looks more unnatural than the wrist on hips pose.

Just here to shed some light on these poses.

They aren't actually "new". I'm 95% certain that the one-hand-on-hip pose is the pose your retainers use when you summon them. And the both-hands-on-hip pose is, believe it or not, something your character has been doing in a handful of cutscenes. These poses have not been made recently they're actually pretty ancient.

I don't think wrists are supposed to bend that way...
