Katrina's Fighting Technique
Tough, but with a feminine charm. I like it a lot, but be worth adapting for Katrina.
I like how in animation you hold on the action for a long time. There are less shots. I want to experiment with doing that. I feel like you absorb the hits more when you hold on the action. It glorifies each hit, rather than over stylizes it.
