Yeah, the pose there is all WTF. The weapons aren't even aligned with the model's forearm, making it look like they don't know how to hold a weapon or like an action figure that had a toy weapon popped into their hand, regardless of how it fits.
Look at the alignment of the weapon model on the right.
This, specifically, is nitpicky when compared to the copy/paste editor job, but it's sort of an amateurish first impression.
Just started a new game, and it's more of a problem with the titan model versus the hunters. My new hunter looks pretty on par with destiny 1 but the titan model and standing pose is terrible. Warlock isn't bad either
