These are all amazing. As others have said they are very expressive but I also absolutely love the manga style they have. They ooze personality. It reminds me a bit of Ryoko Kui’s faces.
Ryoko Kui is super good at keeping the anime style but making characters have very different faces, it's a great compliment!
This style is closer to Tower Dungeon with maybe a little bit of Ranking of Kings, I would say
