Majestic Grunge Black Unicorn Portrait

A grunge style dark and majestic black unicorn marching toward the camera, with a long, flowing mane like dark smoke. Its obsidian coat gleams with highlights, and its spiraling horn glows faintly against a grungy backdrop with gold and brown textures. The unicorn's intense gaze and the haunting shadows create a surreal, otherworldly atmosphere with a sense of foreboding magic.
