It's so obvious I've been re-browsing Aya Kato's amazing gallery.

Admittedly I'm a bit ashamed by how much I drew from her work. I didn't even realize lotuses were a common motif of hers until I was half way done with the picture.

Lol but seriously, pearl necklaces lotus flowers, sorry for the blatantly obvious symbolism >_> It's somewhat hilarious to the point of being crude. Sorry!
