I thought i'd see what would happen if I centred it better and moved the camera closer. Unfortunately I don't think it was enough to fix the issues some people were having from comments here and elsewhere.
I think the issue is that when you're looking at her face and body, everything in your field of view is moving. There's nothing at all that's stationary to pin your eyes to for balance. That's my intuition on it anyway.
I think if I want to try a high-impact speedy animation like that again (which I definitely do!), I need to animate it so that the character moves less from the impact of being pushed by the male when their bodies collide. If that makes sense.
Either way, I thought i'd still upload the better-centred version.
