I often hear music in my dreams. In this case, it was ‘Babylon’ by Oneohtrix Point Never (a.k.a. Daniel Lopatin, for those unaware). I had to respond in the best way possible of course!
I found a Gap ad in a 90s Vanity Fair magazine; the background was completely white, perfect for doodling a background on it. I also highlighted the woman's freckles and lips with a bronze Sharpie.
