text_prompt="Transform this image into a work of art by changing its style and color palette. Apply a distinct artistic style, such as impressionism, cubism, or surrealism, to give the image a unique and visually striking appearance. Experiment with brush strokes, textures, and effects to achieve the desired artistic effect while maintaining the essence of the original scene. Additionally, adjust the color palette to evoke a specific mood or theme. For example, infuse warm, earthy tones for a rustic and cozy feel, or opt for vibrant, psychedelic colors for a surreal and otherworldly atmosphere. The goal is to reimagine the image in a creative and expressive way, transforming it into a captivating visual masterpiece."
