A breathtaking digital landscape painting with thick impasto oil brush strokes texture, reflecting a deep philosophical mood. The sun sets above a dark blue mountain ridge, casting a faint orange glow on the horizon. High in the starry twilight sky, an autumn crescent moon shines brightly surrounded by soft, swirling spring-wind clouds. The canvas visually splits: the left side shows a fine, silky morning mist, while the right side transitions into cold winter snow under a dark night. On a dark hill in the center, a tiny lone silhouette of a xianxia wanderer stands looking back into the vast, misty empty void where nothing is left. Ethereal bioluminescent accents, high contrast, cinematic lighting, melancholic fantasy concept art. --ar 9:16
