石のあごと蛇がうごめく不気味なジャングルの洞窟入口

A high-fantasy, Dungeons & Dragons–style realistic illustration of an ominous cave entrance hidden in the dense jungle at the base of a towering mountain. Massive stone jaws form the cave mouth, cracked and ancient, partially covered in moss and glowing runes. Thick jungle vines, twisted roots, and towering ferns surround the entrance. Dozens of snakes coil across rocks, tree branches, and the ground—venomous serpents with varied colors and patterns, some watching with glowing eyes. Mist rolls out of the cave, dark shadows lurking inside. Dramatic cinematic lighting, moody atmosphere, high detail, fantasy realism, epic adventure art, ultra-sharp focus, 4k, concept art, dark and foreboding tone.
