Cool comic and mostly good advice but I'd make some adjustments and additions :
- Don't ball up your fist, keep your hands relaxed and flex your knuckles right before impact
- Exhale as you're throwing the punch, you'll get a bit more power and you won't get tired as fast if you have to throw some more
- You shouldn't lean into it that much, leaves you open to unpleasant things like getting knee'd in the face
- Best not to "follow through" like that either. Your punches should be snappy and practically bounce off of the nazi's face. This is also conducive to punching more nazis, or punching the same nazi more
