Knight With Glowing Sword Confronts Red Dragon

A full shot of a knight in polished black armor, holding a glowing blue crystal sword, facing a massive red dragon with glowing orange eyes and smoke coming from its nostrils. The knight and dragon are on a rocky, misty mountain peak, with dark, jagged mountains in the background under a twilight sky. The art style is photorealistic digital art with a fantasy theme. The lighting is dramatic, with the blue glow of the sword contrasting with the dragon's fiery eyes, creating a tense and mysterious mood. The atmosphere is cool and misty, with deep blues, grays, and the vibrant red of the dragon. Intricate details on the armor and dragon scales are visible.
