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 [emerald-scaled dragon], set against the backdrop of a [sunset-lit mountain peak]. The tamer should wear [intricately embroidered leather armor] adorned with glowing runes, their expression a mix of fierce determination and deep bond with their dragon companion. The dragon, towering yet graceful, should have [luminous golden eyes] and faint smoke curling from its nostrils, its wings slightly unfurled. Surround the scene with [floating magical orbs] and subtle mist to enhance the ethereal atmosphere. Use a dynamic composition with dramatic lighting to highlight the duo's powerful connection and the fantastical setting.
