Create a realistic and epic image of two dragons of different sizes

Create a realistic and epic image of two dragons of different sizes. The larger dragon is a massive, black dragon with sharp, prickly scales, large, menacing horns and glowing, orange eyes. It sits on a rocky outcrop, and a human figure sits confidently on his back. The smaller dragon stands next to him, with a golden or bronze scale color and smaller, but equally sharp horns. Both dragons are located in a dramatic mountain landscape, with a gloomy sky in the background, which is covered by clouds. The scene should exude a majestic yet threatening atmosphere, with a strong contrast between the dark, large Drachen und dem kleineren, brighter dragon. The rocky outcrop, on which they stand, is rough and marked by scratches and stone chips, which underlines the power and size of the dragons.
