I really wasn’t supposed to spend three days on this.
I really like the theory that Naomi is actually one of the Fates; I picked Lachesis because she’s the one who measures the length of a soul’s life, and is said to choose a person’s destiny after a thread is measured. That’s why her lowered right hand is made of sewing, crocheting, and leatherworking tools. The gold threads she’s manipulating are the puppet-strings of heaven. The albatross head is a reference to the Rhyme of the Ancient Mariner, and the shadows on the human face are in the shape of a spade in reference to the Queen of Spades in French tarot.
There’s an omega sign in her ribcage to indicate she’s sort of the last resort of heaven; the upside down cross is St. Peter’s Cross, to show her reluctance to claim true divinity. Her raised left hand is decked out in surgical tools that she uses as a physician of angels, in Castiel’s “recovery” in particular. Her wings are a shattered mirror as a reflection of Heaven’s poor condition and also her own enigmatic duplicity.
TL;DR: I just have a lot of Naomi feels okay
