Nice!
In my opinion, the animation is too weak right now. Previously, the animations got more desperate and faster as oxygen depleted, kicking her legs and wiggling a lot. She doesn't move much now. And she's very quiet too. Before, she was only this quiet while gagged, which was also kinda boring because she didn't make like muffled sounds while gagged either.
But I do like that now her arms contract like that, as that's what happens when oxygen is cut off from the brain. And the facial expressions are much better too.
