Looking for SFW advice/resources

Sooo… I am normally a filthy wretched degenerate pornographer in SD, but now, I want to use my powers for good!

I am creating a comic for my dad, featuring his and other family member’s faces. I use reface right now, in a1111, but most of my checkpoints are Pony or Illustrious based, and thusly have a very strong “adult” leaning…

I want to make my dad a badass cyberpunk samurai, and feature neotokio style cyberpunk cityscapes, and laserblade sword-fights, among other things.

Anyone that wants to help sharing resources and advice, I would thoroughly appreciate it.
