水中洞窟でドラゴンに立ち向かうライオン戦士

A kickass fantasy scene in an underwater cave with a grizzled, human-like lion dude in medieval garb, clutching a torch, staring at a colossal, dragon-like beast with a massive, gnarly shell and glowing eyes. Sunlight beams down from above, lighting up the mystical, otherworldly vibes.
