he forgot one BIG thing
the enviroment. what will it be? the enviroment is going to be used for the fighters advandage, for either grappling on the monkeybars and kicking the other guy in the face or even ripping out a piece of the enviroment and use it as a weapon, or even toss someone down a huge ass pit. the enviroment is probably one of the most important things for a stick fight to feel original. a white space is barely useful for the stick fighters asernal. and such enviroments may even showcase the figher massive agility. instead of just showcasing its power. you can even make a moving enviroment for more spice. but don't overdo it for it might turn the attention away from the fighters. an enviroment will also help seeing how high the stick man can really jump or how fast he can go from point A to point B. and for even MORE flare, make your enviroment DESTRUCTIBLE. that would showcase the fighters massive power. there may have been a giganic fortess in the beginning but after a furious battle, half of it remains. and the rest into rubble. think of this as an add on to the flash movie Rathanos made. he did have good points to point out.
