A photorealistic street art mural of a massive gray timber wolf with silver-tipped fur and piercing amber eyes howling through the shattered stained glass windows of an abandoned Gothic cathedral, its powerful silhouette rendered in hyperrealistic spray paint with individually detailed fur strands and muscular chest, pale moonlight streaming through broken rose windows casting ethereal blue beams across cracked marble altar, mood haunting and wild yet spiritual, composition centered with wolf mid-howl filling the sacred space, scattered broken pews and toppled candelabras creating religious decay, color palette deep charcoal grays and silver blues contrasted with warm amber candlelight and soft celestial moon glow
