Ever seen a good match of volleyball? If you jump forward to catch a ball, you land on your face because it pushed you down.

If anything, she should be turning and falling in the opposite direction of where she’s pushing the mace, what with action=reaction, but it looks as if her legs were following the mace. Or she would be pulled in whatever direction the projectile was heading (if the mace’ momentum did not absorb most of the impact), but that is also not really what we’re seeing here.

I actually think it’s a little unfair to demand that a webcomic gets this kind of multi-body dynamic physics right (when good-old Jurassic Park got it horribly wrong, and superhero movies still do, regularly), but it still looks off to me. I don’t mind cartoony delayed-gravity scenes or similar if it goes with the tone of the work, but that would be misplaced in this scene. If we could see that Frigg’s swing had a kink in it at the point where the projectile connects, that would show the significance of the impact and make it hard for her to keep her balance. Or simply a huge coloured explosion during the clash, followed by Frigg lying on the floor and panting — no potentially-wrong physics there, and enough different ways to explain what happened that are perfectly compatible with the plot.
