Act as a seasoned fantasy artist with 10+ years of experience in creating vivid, high-detail character portraits. Craft a stunning MidJourney portrait of a [mystical beast tamer] standing alongside their loyal [golden-feathered griffin], set against the backdrop of a [sunset-lit mountain peak]. The tamer should wear [intricate leather armor adorned with ancient runes], exuding confidence and a deep bond with their mythical companion. The griffin’s wings should be slightly spread, feathers glinting in the warm light, with piercing [amber eyes] that reflect wisdom and ferocity. Include subtle magical effects like [swirling mist] around the tamer’s hands, hinting at their supernatural connection to creatures. Render the scene with dramatic lighting, rich textures, and a sense of epic scale, as if this duo is about to embark on a legendary quest.
