"Create a series of high-resolution digital paintings featuring a lone knight kneeling on a beach at sunset. The knight should be in full armor with a cloak flowing behind them and a sword planted in the sand. The scene should evoke a sense of solitude and reflection, with dramatic and vibrant colors in the sky, including hues of pink, orange, and purple. The beach should reflect the colors of the sky in the wet sand, with subtle waves in the background. Use a highly detailed, realistic painting style with rich textures and intricate details, ensuring the lighting captures the serene yet epic atmosphere of the setting sun."
