Joker, laughing maniacally, hanging out of a Gotham City skyscraper window, messy green hair, white painted face, red lips, black suit, purple vest, black gloves, torn black pants, leaning on the windowsill, one leg bent, other foot resting on the edge, urban cityscape background, dark alleys, streetlights, foggy atmosphere, dim lighting, cinematic composition, low-angle shot.
