Apocalyptic valley landscape with massive storm clouds and fire

Digital matte painting rendering massive cumulonimbus cloud formations with golden-hour backlighting and interior flame illumination. Compositional focus centers on deep valley terrain with distributed fire hotspots and atmospheric fog layers. Small bird silhouettes traverse midground; foreground anchored by rocky outcrops. Tonal palette dominated by blue-grey smoke transitioning through warm amber-orange flame cores. Volumetric light scattering and atmospheric perspective establish extreme depth. Rendering exhibits photorealistic cloud physics with painterly landscape treatment.
