Not much to say about this. Just drew Twilight laying down on a black background and the rest just sort of happened.
This is done on one layer with the marker tool (blendy settings) and another layer with a golden-yellow linear burn on about 60% opacity. I can make a non-burn one available if you wish.
Time taken: ~1 and 1/2 hours
