Ancien arbre-monde s’élevant d’une île flottante dans les nuages

A breathtaking fantasy landscape featuring a massive, ancient world-tree growing from a floating verdant island suspended high in a bright blue sky. Long, ethereal waterfalls cascade from the edges of the floating island, cascading down into a sea of soft, white clouds below. The tree has a thick, textured trunk with sprawling branches covered in lush, vibrant green foliage, with long vines and roots hanging gracefully into the void. Surrounding the central island are other smaller floating landmasses with dense tropical greenery. The composition is a vertical wide shot, emphasizing the immense scale and height of the scene. The lighting is bright and cinematic, with warm sunlight illuminating the treetops and creating a sense of awe. The color palette is dominated by deep forest greens, brilliant azure blues, and crisp whites, evoking a serene and magical atmosphere. The art style is high-quality digital illustration, reminiscent of epic fantasy concept art, with sharp details and a dreamlike, majestic mood.
