I like what I have seen so far. One thing that can make the matches more competitive would be for the girls to battle for the top position instead of the girls taking turns all the time. The taking turns makes the match seem more predetermined than an acctual battle.
This could be an idea for the next ones to have the coach that's there to not only teach the trib positions before the fight, but also maybe the fight dynamics or competitive edges like how to transition to top position in order to have more of an advantage? (Think of brazilian jiu-jitsu or wrestling transitions but that does get complicated for these first timers and we don't want them to take direction since this is their authentic selves trying to do whatever it takes already to win and learning the trib positions might be too much to ask already to keep it all authentic) Just remember that these models may already be nervous or have second guesses about the trib positions that are all new to them prior to the fight.
But with more experience and based on the authentic personality of each model, I can see some of them naturally doing this on their own once they get the hang of the match dynamics. But if you can post some samples of fighting for top position that you like the best from the past era, it's definitely possible down the line for them to learn before the fight starts.
At the end of the day they are only given 3 guidelines:
1. Fight for REAL and make it competitive (be their authentic selves)
2. That their pussies and clits must always have contact (otherwise it's not considered TRIB. They are told it's cheating if one of them rubs her groin or thigh on the other's pussy because it's not equal sex stimulation and tribfighting is the name of the game)
3. Only pussy-to-pussy/ass-to-ass positions are allowed
