Here's the 14th card, temperance! Inspired by very ordinary seraphim like angels, no 8 wings, not covered in eyes, no multiple heads, no "be not afraid".
Just 2 grails that she's pouring into each other, which I've taken from the Magician card for consistency.
Aside from that, mostly inspired by Alfred Mucha and the Psychick sisters from One Punch man.
And some MTG cards.
