They confront a colossal, three-headed dragon, its scales richly textured with muted colors, lending an ancient and formidable aura. The forest setting features sharp, clear lighting and natural, understated colors that emphasize the crisp details of the characters and surroundings. The atmosphere captures the tension and grandeur of the impending clash.
