Spider in a Dragon's Lair (Digital Fantasy)

An ultra-detailed digital artwork of a spider weaving a luminous, iridescent web inside a vast dragon's cavern-lair. The dragon lounges in shadows above a towering hoard of gold and gems, its scales catching warm amber light. The cavern is lined with stalactites, rune-carved stone walls, and bioluminescent fungi that cast a soft glow. The spider glows with cool silvery-blue bioluminescence, eight eyes reflecting firelight, dew-like droplets on silk. A dramatic low-angle composition shows the spider in the foreground on a shimmering web, with the dragon's hulking silhouette and treasure in the hazy background. The scene uses cinematic lighting, high dynamic range, and painterly digital brushwork, with a color palette of golds, emeralds, and deep purples. High-detail textures on silk, metal, and stone; 3D-rendered feel with dynamic shadows and atmospheric fog.
