Hello! Maybe you will try to make a new damage system for game?
Or make it like a mod for game.
My idea is:
points of damage
1. Head (50% of damage)
2. shoulders ( 10% of damage)
3. Upper belly (40% of damage)
4. Middle belly (20% of damage)
5. Lower belly (15% of damage)
6. Hips (10% of damage)
next idea is make all without HP for all character.
All "points" have a 100% HP. and when HP is done is make a next situation for animation character.
1. Head - dizzy, fall on spine after punch in head.
2. Shoulders - character not make a power punch by hands
3. 4. 5. All belly. Fall on knee and bend over, after all punch in this area.
6. Hips - character not make a power punch by legs and dizzy.
After 3 points is done of HP character is lose.

Your ideas are great, but I think the "body part damage" is ok, but not the latter part. it is not suitable for a fast and quick match game like Dragon Fury. Better used for game which has "survival" element game that player need to deal with negative effects after getting damaged. Besides it is not enough time for player to "feel" those affection, unless the match last longer. For combat game inspiration like this, time of a match might be very very short.

Yes, but is idea for make a mod for game. Think is interesting.
