A photorealistic street art mural of a massive anatomically correct human heart with pumping ventricles and delicate coronary arteries erupting through the cracked tiles of an abandoned 1960s medical clinic, its organic surfaces rendered in hyperrealistic spray paint with glistening wet textures and vein details, harsh fluorescent hospital light streaming through broken operating room windows casting cold clinical beams across scattered medical instruments and toppled morphine bottles, mood haunting and vulnerable yet surprisingly hopeful, composition dramatic with heart center-frame filling the examination space, broken X-ray viewers and fallen patient charts creating medical decay, color palette arterial reds and pink flesh tones contrasted with sterile hospital whites and cold green surgical glow
