Create a hyper-realistic digital painting depicting an ancient cosmic tree portal for the cinematic double-exposure portrait poster seamless blend. This colossal, gnarled arboreal titan stands as a gateway, its deeply furrowed bark not of wood, but of swirling galaxies and glittering nebulae. The mighty trunk reveals an infinite cosmic void within its core, while its sprawling canopy transforms into an intricate tapestry of distant stars and ethereal gas clouds, merging the organic with the celestial. Details to include: Ancient runic symbols subtly etched into the cosmic bark, shimmering with starlight. Wisps of vibrant nebulae spiraling gracefully from the tree's uppermost branches like celestial tendrils. Faint, pulsating starlight emanating from deep within the trunk's cosmic portal, hinting at untold dimensions. Tiny, bioluminescent forest sprites and fireflies orbiting the tree, appearing as miniature planets. One colossal root transforms into a streaking meteor, leaving a radiant trail of stardust. The environment around this celestial anomaly is a desolate, mist-shrouded ancient forest floor, barely discernible through the cosmic glow. The ground is carpeted with luminescent moss and the fragmented remains of forgotten, lichen-covered stone ruins, imparting a profound sense of forgotten time and deep mystery. In the far distance, ethereal mountain peaks pierce a hazy twilight sky, their silhouettes softly reflecting the faint, otherworldly luminescence of the cosmic tree. Ethereal and mystical lighting permeates the scene, with a soft, pulsating cosmic glow emanating directly from the tree, casting dramatic, elongated shadows across the ancient forest floor. A captivating interplay of warm purples, deep indigos, and cool blues from the cosmic nebulae creates a dreamlike and profound luminescence. The overall lighting is intended to evoke intense wonder, profound awe, and a subtle hint of melancholic grandeur. The color palette is dominated by deep indigo, cosmic purples, stardust golds, shimmering blues, muted deep forest greens, mossy browns, and ethereal whites. The mood is profoundly awe-inspiring, ancient, magical, and infinitely mysterious.
