황혼에 홀로 선 인물이 있는 초현실적 생물발광 도시

A surreal cityscape where towering, bioluminescent skyscrapers intertwine with ancient, overgrown ruins. A single, solitary figure, their back turned, gazes at the horizon. The sky bleeds with vibrant, impossible colors, and a distant, faint smile seems to emanate from the city's energy itself. Rendered as a retro sci-fi poster with vibrant, vintage color grading.
