Mystical Portal and the Cosmic Landscape Beneath the Tree

A towering, textured tree trunk dominates the left side of the composition, a swirling, ethereal, galaxy-like portal glowing within a hollow in its bark. emanates a soft, otherworldly light, illuminating a small, cloaked figure standing at the base of the tree. The figure gazes up at the portal, where a shadowy entity can be seen within. The backdrop is a vibrant, swirling nebula of deep purples, pinks, and blues, speckled with countless stars. Bare, silhouetted trees stand on the right against the colorful night sky. The ground is covered in wispy grass, rendered in deep blues and purples. The overall style should be reminiscent of Andy Kehoe, with intricate details, rich textures, and a dreamlike, slightly melancholic atmosphere. Emphasize the contrast between the dark, textured tree and the vibrant, swirling nebula, and the smallness of the figure against the vastness of the cosmos. The light from the portal should cast a subtle, otherworldly glow on the surrounding grass.
