Generate an image of the front facade of an abandoned hospital, portraying a haunting and desolate scene. The hospital should be depicted as weathered and deteriorated, with cracked walls, broken windows, and overgrown vegetation engulfing the exterior. Emphasize the sense of abandonment and decay, with signs of neglect such as peeling paint, sagging awnings, and rusted fixtures adding to the desolate atmosphere. The surrounding area should be devoid of life, with empty streets and overcast skies contributing to the eerie ambiance. Incorporate elements that hint at the hospital's former function, such as faded signage, boarded-up entrances, and remnants of medical equipment scattered about. The overall mood should be one of loneliness and isolation, as if the hospital has been forgotten by time and civilization. Utilize lighting and composition techniques to enhance the haunting atmosphere of the abandoned hospital facade, creating an image that evokes a sense of melancholy and unease in the viewer.
