An enormous ancient forest spirit with a weathered bird-skull mask, twisted branch-like antlers, long shaggy fur, and a flowing beard of moss and lichen. Misty ethereal forest background with silhouetted pines, muted sage-green and brown palette. A forgotten nature deity, botanical growth, mystical woodland guardian with detailed organic textures. Illustrative art style, vertical composition. In front stands a small girl seen from behind, among abandoned trees. Dark fairytale or gloomy anime atmosphere, evoking Nordic myth of trolls and elves.
