A photorealistic street art mural of a massive hummingbird with iridescent emerald and ruby feathers hovering in the gutted interior of an abandoned clock tower, its delicate wings rendered in hyperrealistic spray paint with translucent wing membranes and rapid motion blur, dusty golden light streaming through broken clock faces casting warm beams across scattered vintage timepieces and fallen clock hands, mood magical and fleeting yet melancholic, composition dynamic with bird mid-hover filling the vertical shaft, broken gears and toppled pendulum mechanisms creating time decay, color palette vibrant jewel greens and deep rubies contrasted with warm brass golds and soft amber daylight
