Full body of a cheerful, smiling woman dressed as a cowgirl knight riding a majestic horse, her attire a blend of rugged Western charm and ornate knight armor, accented with elements of a Venetian carnival. She exudes a sense of joy and strength, as if ready for battle, under a vibrant, warm sunset. The scene is captured in high resolution with hyper-realistic detail, resembling an oil painting by Frank Frazetta, infused with rich, vivid colors and dynamic brushstrokes, creating an atmosphere of adventure and celebration.
