I recommend multicharacter, it works great on PonyXL and you get ability to made images with 2 or more characters by prompt without problems with regional prompter technics(and even with it better than use 2 different LoRAs).
Donation Link(if you donate more than 10$ you can write character name + title name to tip and it high changes i do this character later(not next one, just add to my current priority queue on end~or little closer)):
