Enchanted Grove Troll - Concept Art

Concept art of a colossal troll standing in an enchanted grove. The troll has rugged, moss-covered skin with gnarled horns and glowing rune-like markings on its arms. He is surrounded by bioluminescent mushrooms, luminous moss, and ancient trees with hanging vines; soft emerald and sapphire light filters through a misty canopy. A crystal-clear stream winds around gnarled roots as firefly-like motes drift in the air. Painterly, high-detail textures on skin and flora, cinematic lighting, depth of field, and a sense that the troll is the guardian of the grove. Fantasy illustration, concept art style.
