Jump animations are a nice addition. Landing visual is spot on. It is a bit floaty while in the air, maybe include slight arm motion indicating ‘balancing’ while airborne.
Katana is nice. There is a strange sword-salute at the end of one animation that is kind weird – edit for clarity. No anime, please. This is Conan.
Other animations to consider:
z-axis rotation while stationary – body twists, then legs/feet follow stepping left or right. Looking up and down works well, when following targeting pointer, same should happen when looking/moving left and right. Can also consider look left or right while running/walking – while_pressed toggle for vanity view. Long_press becomes “while_pressed” short-press is toggle. (see other games) When in rp, it is very artificial and immersion-breaking when players swivel like mannequins.
Alternate idle animations; see the mod. Add custom feature, if a player is standing still and plays more than one emote, those emotes begin a rotation, until player moves in x-y axis.
Unconscious and injured animations. See recent mod that adds alternative downed and injured animations.
Unreal animation tech should be fully leveraged.
