This concept probably exists in multiple pieces of art already but I wanted to snatch at low hanging fruit of ideas I guess. I posted the sketch for this here.
I actually didn't have colors in mind while drawing this, so it was interesting to try to figure out what was what.
I interpreted "ethereal beauty" of elves with glowing because I'm a simple man.
