A full body portrait of a fierce female knight with the spirit of a cowboy, clad in intricately detailed medieval armor, confidently riding atop a majestic horse. In one hand, she skillfully wields a gleaming flintlock pistol, while her other hand brandishes a powerful firearm, each piece reflecting the sun's light. Behind her, a breathtaking panorama of imposing mountains stretches towards the horizon under an expansive blue sky. The scene is rendered in high-resolution hyper realism, capturing every texture and nuance in the style reminiscent of a masterful oil painting, inspired by the dramatic and dynamic artistry of Frank Frazetta.
