A magnificent ethereal horse made entirely of glowing blue and purple flames and energy, rearing up majestically against a dark stormy sky, its mane and tail flowing with luminous electric blue fire creating dynamic swirls and wisps, the horse's body composed of brilliant sapphire and violet flames with lighter cyan highlights, standing on dark rocky terrain with sparse grass and small trees visible in the misty background, dramatic atmospheric lighting with storm clouds and a hint of moonlight filtering through, the mystical creature radiating power and freedom with intense glowing energy particles surrounding it, shot with a wide-angle lens at f/2.8 for shallow depth of field emphasizing the glowing horse, fantasy digital art style reminiscent of magical creature illustrations, color palette dominated by electric blues, purples, and deep blacks creating strong contrast, cinematic composition capturing the wild untamed spirit of freedom, resembling concept art from fantasy films with ethereal magical realism aesthetics.
