A red dragon flying over a stone stairway in front of a castle

"A gigantic, morbidly obese red dragon lying on its back in a dark cave filled with an abundance of gold and treasures, with its immense soft belly colored in a pale yellow hue. The dragon's eyes gleam with a vibrant glow as its wings sprawl out, casting a shadow over the hidden riches. The cave is dimly lit, with rays of light streaming in from small openings, illuminating the dragon's massive form. The artwork should have the best quality, with ultra-detailed features, realistic rendering, and vivid colors to bring out the awe-inspiring presence of the dragon. The style should reflect a fusion of 2.5D digital art and concept artists, creating a unique and visually captivating composition."
