I think having a preset system is going to be my next port of call for v2, having just a single setting often doesn't work particularly well for certain poses and orientations so switching presets by trigger is something I'd like to implement
VAMMoan triggers a few things in that scene, including Timeline for the facial expression and head movement. Facial expression is from AshAuryn Sexpressions, combined with a crossed eyes morph, links below.
I did play around with that but without dictating directions for each individual body part, once you start getting too many parts you just kind of jiggle the whole atom as a whole instead of relative trembling. It's something I can iterate for V2 fairly easily though
