Whenever I see people try to do RPG theming in smut or bondage are it's always really obvious whether they've played an actual RPG before or their only frame of reference is hoyo's gacha slop
I have in the recent past raised them significantly while seeing INCREASED demand afterwards, it is totally doable. I did this on my old account that had 3k followers less than you. The real limiting factor I would say is not prices so much as that using the sheets loses you clients. They just aren't good for catching attention in the feed, too much info all at once makes people scroll past and so do prices above like $60 or $70. In my experience posting something like "Commissions are open, DM me and let's discuss" with a few selected pieces of your work attached nets way more messages, many of which will not turn away when you tell them the prices.
@mbopsss Hi mbak it's been a while. Just do it. You have over 9k followers, there's going to be people who will pay whatever you're asking. People can't really get by reasonably going off complaining about it when it's a luxury good in the first place.
