Act as a masterful fantasy artist specializing in ethereal character portraits, with expertise in magical aesthetics and intricate rune designs. Create a stunning MidJourney portrait of a [MYSTICAL ENCHANTER] with [GLOWING GOLDEN RUNES] swirling across their [ANCIENT ROBES] and skin. The enchanter's eyes should radiate an otherworldly [SAPPHIRE BLUE] glow, hinting at their immense arcane power. Surround them with floating fragments of forgotten spells, rendered in a hyper-detailed, cinematic style. Use a color palette of deep purples, shimmering golds, and twilight blues to enhance the magical atmosphere. The composition should be portrait-oriented with dramatic lighting that makes the runes appear to pulse with energy. Add subtle particle effects to suggest a constant flow of magic around the character.
