Knight of the Arcane Realms - Concept Art

A highly detailed concept art scene of a lone knight in a magical realm. The knight wears ornate plate armor with iridescent blue-green highlights, gold filigree, and glowing runes along the edges. A long, rune-carved greatsword rests in one hand; the other grips a heraldic shield bearing a phoenix crest. He stands atop a mossy precipice as floating islands loom in the distance, connected by luminous bridges and crystalline arches. Bioluminescent flora glows at his feet; crystals and wisps float in the air; waterfalls of light cascade between islands; an aurora shimmers in a violet-pink sky. Dramatic cinematic lighting with warm rim light on the knight, cool ambient light from the realm, and volumetric fog. The scene is rendered in a bold, painterly concept-art style, suitable for a fantasy epic. Composition is a three-quarter view from a low angle; cape and hair flutter in the wind; shallow depth of field keeps the knight sharp while the background sweeps into a grand, dreamlike landscape. Color palette: cobalt blue, emerald green, gold, and magenta. Style cues: digital painting, ultra-detailed, 8k resolution, concept art for a fantasy universe.
