Alien Knight in a Medieval Realm — Concept Art

An alien, tall and slender with iridescent emerald skin and a smooth elongated head, wearing ornate brass-and-onyx armor that seems grown around its frame. The scene is a moonlit medieval city: torch-lit streets, towering stone castles, and market stalls. Runes glow on the armor as if channeling ancient tech. The alien stands in a three-quarter view among armored knights and villagers, with calm, curious eyes. Style is concept art / matte painting with painterly textures, cinematic lighting, and high detail—weathered stone, intricate fabrics, subtle fog, long shadows, and warm torches contrasting with cool blue glows. Color palette includes ochre, brass, iron, teal, and gold.
