I like Chaos Spring but I also didn't think Chaos Thrust even needed an upgrade, Full Thrust maybe needed an animation upgrade but it needed to be small and similar in animation and sound to the original, Heavens' Thrust feels more like an aoe, I would actually like it if it was the animation for Draconian Fury which I dislike.
If anything the only thing that needs an animation and sound upgrade is Vorpal Thrust.
