Let's see...I can see the Triforce from the Legend of Zelda, Peach's crown, and Ruby Rose's symbol/crest. The crescent moon's making me think of Sailor Moon, but that's a complete guess. The other three I have zero clue on.
Does seem there's a general theme of power/purity going through it (rather fitting for KH :P) - Ruby Rose is a straight-up hero with some serious silver-eyed powers, the Triforce gives omnipotence to anyone whose heart is sufficiently pure and balanced (everyone else needs to find two random destiny-touched individuals to get their wishes granted), and Peach is a cinnamon roll who's occasionally shown some impressive powers (mainly in the spinoff games).
Love the divine gold-and-white colour scheme for this - fitting for the Light part of this equation.
