Nice job! That's really impressive work.
Is the granny driven by physics while she's walking? It seems very consistent, like an animation, but there's nice secondary animation on the fluid sack on her zimmer frame, which makes it feel like it's physics. Obviously when she's been knocked over I can tell she's a ragdoll, but I can't tell while she's walking.
It's good either way, I'm just curious about whether you got a ragdoll that consistent.
