Congrats for beating it. Mother is a serious thing.
I don't know if your Pinkladies is Heavenly Flower's Young Lady Pinkladies or if your Pink is Pink Miko but thoses two are good against Mother too. They can help you in the future for clearing Mother to complete the "do Mother X times" quests.

Next step is Laeva. Good luck. He's the hardest boss currently. But I'm pretty sure you can do it.

Also, you should try to get Balsam soon with her Reissue. She is a good alternative to RRose.
