I would love for tweaks to be made to Elezen.
I want them to have slightly shorter arms and slightly bigger heads to make them more like the concept art (which have silhouettes different than the hyurs)

Another hope is to choose our character's idle stance which we can do in game through timing and /cpose it just doesn't show in cutscenes. It would be nice to select a a resting stance for cutscenes.
....more character customization tweaks in general, I guess I'm saying.
