Have you ever seen a Labradorite? Well Reykah eyes are like that mineral. Labradorite it's a grayish stone with yellow, green, blue and violet reflections when viewed from certain angles.
I took inspiration from that mineral for her eyes design, while for some of her feathers I looked up some peacock feathers. Some other stuff like her wings shape and her "tail" (she doesn't actually have a tail she just has some very long feathers) are inspired by a specific kind of butterfly (morpho peleides) 😊 I still have to figure out some of her design but hope ya like her for now 😊💕
Just an example on how their wings are c:
At first Reykah wings are way more original but Jeremy has a little secret.. ehehehhe *mysterious face*
As you can see their wings are totally different and Reykah has no tail but their coach has found a way to make them fly with the same skills. I really don't know who would win in a battle between them cx
