It's not that her position isn't dynamic. It just doesn't do justice to the action being shown. Too flat and lifeless. the bare minimum for translating this throw.

This is much better in the sense that you can really tell the target has been thrown. The composition is more pleasing and leaves room for backgrounds, sound effects or speech balloons....but still it could be better. I'd use this angle if the target was going to hit something important or was going to get out of the damage by landing on his feet.

To show this move took him out of commision, we need some closure.

Booooom! Choosing an angle that shows the moment of impact really pulls this action together..in one frame you can see that the target was thrown...travelled a long distance..and landed hard. Arms and legs akimbo! Again..curved motion lines along the trajectory of the throw parlay the action.
