A ancient green man tree

An ancient, gnarled tree man with moss-covered bark-like skin, leaves for hair, and glowing emerald eyes, set against a rich, contrasting backdrop of warm golden hues and deep blues, evoking a sense of mysticism and wonder. The atmosphere is dense with mist and foliage, with intricate, organic details and textures, reminiscent of the fantastical worlds of Zdzisław Beksiński, Simon Stalenhag, and Brian Froud. The image is rendered in a highly detailed, 8k resolution, with a deep color palette and subtle, nuanced lighting, as if illuminated by an otherworldly glow, perfect for a fantasy concept art splash screen trending on Artstation, created with the cutting-edge technology of Unreal Engine 5.
