Dark Monster Behind

Create a dark, supernatural cinematic poster. Show the same person from the reference, with an intense gaze and a slight nosebleed, wearing a blue jacket over a white shirt — standing at the center of the frame, staring directly at the viewer with a serious, focused expression. Behind the character, reveal a tall, eerie humanoid monster formed from smoky shadows and alien-like flesh, towering over them as a looming threat. The creature should have no visible eyes, an elongated head, and a disturbing vein-like texture — emerging from blue fog. At the bottom of the scene, place one person riding a bicycle across dark, misty ground — the bicycle moving from left to right, slightly illuminated by an otherworldly blue glow, creating a sense of mystery and urgency. The overall mood should match the supernatural tension of the Upside Down: dense fog, volumetric blue lighting, floating dust particles, high-contrast shadows, and a cold cinematic color palette of blues and blacks. Ultra-realistic 8K detail, eerie atmospheric depth, dramatic lighting, no title text anywhere.
