A vibrant and surreal landscape illustration featuring a dreamlike valley surrounded by cascading layers of colorful, undulating mountains. Each layer is painted in a gradient of vivid hues, ranging from deep blues and purples at the edges to fiery reds, oranges, and yellows closer to the center. The intricate texture of the mountains creates a flowing, wave-like appearance, enhancing the surreal quality of the scene. A glowing, golden river snakes through the valley, guiding the viewer’s eye toward a distant, majestic peak that stands illuminated under a twilight sky. The sky transitions from a dark, starry canopy at the top to warm gradients near the horizon, creating a harmonious balance with the landscape below. Whimsical, swirling clouds frame the scene, adding a sense of motion and depth. The art style is rich and detailed, with a focus on vibrant colors and fluid shapes, evoking a sense of wonder and transcendence. The overall composition feels like a journey through a fantastical, otherworldly realm that captivates the imagination.
