I’ve seen so many glorious Harry Potter headcanons drawn over the years, but I don’t think I’ve ever seen Luna (my favourite) portrayed as anything but white in fanart? Not that I’m not sure it’s happened somewhere, and probably much better done than this, but-
-here’s my shot at a WOC Luna, anyway. She’s not a painting, I want to stress that, she’s a manip. She’s made of lots of different pictures – her eyes are Lupita Nyong’o’s, for example, and her arm is Emma Watson’s, and her outfit is obviously Luna’s original outfit from Order of the Phoenix. I put all of ‘em together to make this, ran it through a lot of filters, and carefully used the smudge tool (a lot) to give it a painted sort of effect. (It’s an experiment I’ve tried before, actually.) Hopefully I captured her essential Lunaness.
tl;dr = here is Luna in a forest with a flower crown practising some wandless magic.
