A powerful female knight in majestic medieval armor sits atop a sturdy horse, embodying the spirit of a rugged cowboy with a touch of elegance. She holds a gleaming flintlock pistol in one hand and a vintage revolver in the other, her eyes scanning the vast landscape. Towering mountains stretch across the horizon under a vibrant, cloud-dotted sky. This high-resolution, hyper-realistic oil painting, inspired by the dramatic style of Frank Frazetta, captures the fusion of ancient chivalry and wild frontier spirit against the awe-inspiring backdrop.
