A full body scene of a joyful woman depicted as a cowgirl-knight, confidently riding a horse. She exudes happiness with a cute and charming smile. The setting is a vibrant Venetian carnival where she's engaged in a spirited skirmish. The scene unfolds under a breathtaking sunset, rendered in high resolution. The style is hyper-realistic, reminiscent of an oil painting by Frank Frazetta, capturing the dynamic energy and vivid colors in the artwork.
