Stanley and Judith the flute lady.
At one point in the novel Stanley used his bird book to fight against It in the Standpipe by chanting the names of bird species. And, I depicted him with the a singing rose, since, in the novel, he seemed to be aware of them(strong hints he probably had the Shine.) I've depicted him with the roses before, and his favorite bird, the Black-capped Chickadee, since I like to explore the subject of his knowledge of different world(possibly the Tower even.)
The birds flying are glowing green, as sort of a depiction of Maturin's energy. Perhaps he gave Stanley the courage to fight against It(Although Maturin said he doesn't interfere, so maybe not, but I like the idea.)
