Assuming you still desire input, in response to the poll... (I'm elaborating to defend my answers, Cause I'm feeling chatty)
1. A, then B, then A (I would not be against a tail at Rachel's waist, but I think it would suit the headmaster's kink more to get her a buttplug tail after she says she wants a tail to feel more like a cat, and then he could replace it with a tail on a belt after she complains and says she'd rather not wear the buttplug one, but then have then have her eventually request the buttplug version, as she gets more explore-y of her sexual side.)
2. A - I want there to be more going on at the beach in general. (This could maybe eventually pay off by having half the volleyball court be "accidentally" on the nude side of the beach with an eventual optional rule for mandatory nudity on the nude side? So after a few hoops, and a rules change, suddenly only one team gets to wear clothes at a time?)
3. B - I'm fine if you keep the sweaters, but I don't want the girls to overheat in a heat wave. (I'd like if this lead to passing a rule specifically designed to get girls to remove clothing "for their own health." It sounds like something Ruth would be behind, and if there was a loophole that allowed the headmaster to strip girls more by turning on a heater during punishments, so much the better!)
4. C - Sally and Claire administer punishments to twins, HM wanks like nobodies business in the corner (Ok, seriously, it should be B. Claire needs more practice, and the headmaster could be like, just repeat what I do to this butt to that butt, lol)
5. C - Debbie would get too much pleasure from private punishment, and Clarie would likely still feel too empowered. Together, they would balance the experience for each other by causing each other just a little bit of embarrassment at their own reactions. (Also, the inevitable three-way of this trio could be hilarious with HM and Debbie trying to show-off by making Claire orgasm harder than the last time.)
6. C - Keep tattoos and piercings out of SLAG (Actually, I like piercings and tatts, but most schools, even those without authoritarian leadership, don't allow many piercings, and tatts just scream "the owner of this art at least 18 years of age." The story already explicitly says this of all of the girls, but there is currently little visual dissonance if a player chooses to ignore those lines of text. If you want to add a girl with tatts or piercings, it would not detract for me, but I'd be upset to learn that Donna went out and got a tramp stamp and subdermal spines, as an example.)
7. C - The pubic hair is in balance, and all is well. (The variety is nice, great job!) To be honest, it would be AMAZING if you could create a line of BS that would have Ruth agree to mandatory Brazilians for all students though. Bonus points if it does not involve an infestation of pubic lice.
8. B - You do what the story needs, regarding punishing the girls, and draw the line where you want, I'm down for your tale. (Whatever you go with to keep the most people content is FINE by me. Zero drama here whatever option you go for.)
9. A - Preggers girl/girls as an option is fine with me. I think timing-wise it makes the most sense if a new girl is introduced already showing, (NOTE: I don't count this as NTR) but the HM should have to approve the transfer for a pregnant student, and I can even imagine Mykock saying he would understand if it was outside of HM's comfort zone. Otherwise, it seems like you would be ignoring how an established girl that theoretically "just" got pregnant is suddenly with bump, or full belly only a week later? Or else there is little visual payoff for knocking the girl up? Or you wave the psudo-magical science of miss Chang at it and say she developed a way to accelerate the pregnancy so the baby could be here before graduation? Or you go hardcore realism, and maybe render each scene baby-mama could be in differently, so the correct one can play as time passes and the baby develops, which sounds like waaaaaay to much work for a game.? Or just add the whoever-and-I-got-together-after-I-knocked-her-up story as an epilogue with a few renders for an alternate ending like a lot of games do.
If your response to those options is "why bother?"...
Introducing an already pregnant girl would mean the HM would need to come up with innovative ways to punish her, as spanking/paddling/caning would be ill-advised with a baby-on-board. Maybe the nurse has to consult or even come in to observe punishments for the baby's safety? HM could go for something like nipple clamps, or breast spanking, and he could even spout off some theory about needing to prepare her for the pain that comes along with breast feeding. (With any content added, I am pleased, and the only complaint I could even think to make about optional content that I actively wanted to skip would be that your valuable time is less available to devote to things I prefer, which would be right crappy of me, as everyone deserves to get a game that meets their interests. Besides, even I can agree that Priti's Impromptu Porn Career would be a much worse game with far less variety, so it's a good thing I don't make the design decisions! lol)
(Thank you for making a fantastic game, by the way)
