High-contrast monochrome grunge illustration. Rough charcoal and chalk texture on concrete wall. Abstract street-art aesthetic. Distressed noise, scratches, dust, film grain. Primitive hand-drawn elements: crude cartoon face with hollow eyes and clenched teeth, uneven outlines. Fragmented symbols and arrows scratched into surface. Dark vignette, heavy shadows, low-key lighting. Subtle surreal mood, ominous, raw, underground zine style. Imperfect composition, asymmetrical balance. Text appears hand-carved or chalked, partially erased, worn, uneven lettering. Analog decay, photocopy artifacts, lo-fi horror editorial feel. No color, pure black, white, and deep gray. Static, gritty, unsettling atmosphere suitable for experimental video sequence.
