A glowing black horse coming out of the forest

A majestic, glowing black horse, its coat radiating an ethereal aura, emerges from the shadows of a mystical forest, its presence illuminated by dynamic, volumetric lighting. Hyperdetailed, intricately rendered foliage surrounds the horse, as if the forest itself is alive. In the style of Greg Rutkowski's dark fantasy concept art, with the opulent, flowing lines of Alphonse Mucha and the atmospheric, cinematic lighting of Jordan Grimmer. Rendered in 8K resolution, with deep, rich colors, and a bold, contrasting palette of purple and yellow, evoking a sense of wonder and enchantment, as if plucked straight from a trending Artstation splash screen, crafted with the photorealistic precision of Unreal Engine.
