I watched Doctor Who: Flux and was inspired by *spoilers*. So long story short and spoiler-free, here are the colors of the promo pics/logo of the Flux Series melting down the 13th Doctor's wings like crayons as she seemingly turned to stone. Hence the name, "Fluxing Angel". And yes, I had to stare at this Weeping Angel photo for hours, utterly terrified of it coming to life and in awe of this episode capturing the horror of the Weeping Angels. Plus, I also took the background from what happens to the Grand Serpent in Flux's finale (watch to know, my nerds;).
This piece is 18"x24" and took maybe 20-30 hours to complete. Plus, this was my first time every making something as colorful as the 13th Doctor's outfit into black-and-white freehand. The guesswork was worth it, though!
