A vertical, ultra-detailed digital painting of a cosmic scene in warm golden tones. A gigantic translucent ring hovers in a swirl of amber nebula, gently wrapping around a sun-like planet inside. The inner sphere glows with pale light while the outer ring casts soft reflections and shadows on surrounding clouds of gold and bronze. The background is a deep space field filled with twinkling stars, glowing dust, and wispy nebula filaments. The mood conveys celestial harmony and mystical fantasy, with cinematic lighting, high contrast, and a soft haze. Style: photorealistic sci-fi concept art, painterly textures, extremely detailed, 9:16 aspect ratio.
