A majestic scene of a powerful female knight-cowboy riding confidently on a steed, clad in intricate medieval armor shimmered with hints of gold and silver, her posture strong and commanding. She cradles a beautifully carved flintlock pistol in one hand, a more modern handgun poised in the other, embodying a fusion of eras. The backdrop reveals sweeping mountain ranges, their rugged peaks piercing a vibrant blue sky dotted with wisps of cloud. The landscape is captured in hyper-realistic detail, executed in the dramatic and dynamic style reminiscent of Frank Frazetta's masterful oil paintings. The atmosphere is one of adventure and timeless strength, woven into a high-resolution tapestry of color and light.
