So I made a portrait pack for this game, but because I don't use F95, I can't post a link to it here. You can find it on the dev's website, unsurprisingly under "portrait packs."
At time of posting it's a little over half done, with 30 of 48 All 48 Chosen portraits are done and ready to go, each with a civilian transformation as well.
All images created with NovelAI, I take no credit for their existence, etc, etc,
EDIT: Each girl has two extra expressions in this pack, Smug, and Used.
The game doesn't call these, (As of v37 it does) they're meant to replace Joy and Lewd, depending on the girl's personality and corruption. Make your own judgement call as to when to swap them out. Or do it immediately if you like them better. I'm not your dad.
UPDATE: As of version 37, Smug and Used now replace Joy and Lewd when used by Forsaken. Big thank you to CSDev for adding native support for my portraits.
