Muscular lightning woman flying in a dramatic fantasy sky

A vertical fantasy illustration in the style of a classic 1990s oil painting book cover, rendered with a semi-realistic, painterly aesthetic reminiscent of Boris Vallejo and Frank Frazetta. The central subject is a muscular, tanned woman with a highly athletic, hourglass figure, floating or flying upwards in a dynamic, arched pose against a dramatic backdrop. She has long, voluminous brown hair with blonde highlights that streams wildly to the right, suggesting intense wind or electrical energy. Her skin is rendered with a glossy, oiled finish, highlighting her abdominal muscles, quadriceps, and shoulders with a rich bronze-tan hue. She is wearing a minimal white costume consisting of a white bra-like top and high-cut white briefs; a jagged white lightning bolt design runs down the side of her left hip and thigh, and another white lightning motif is visible on her upper torso near her right breast. Her right arm is raised above her head with a clenched fist, while her left arm is outstretched to the side with her hand open and fingers splayed, as if she is casting or controlling the lightning. Jagged white and yellow lightning bolts crackle around her upper body, particularly near her head and outstretched hand, branching out into the sky with sharp, electric detail and bright white cores. Her facial expression is intense and focused, with defined cheekbones, dark eyes looking slightly upward, and lips slightly parted. The background is a turbulent, swirling sky filled with volumetric, smoke-like clouds. The top left is a bright, glowing yellow-orange, suggesting a sunburst or intense energy source, which transitions smoothly into deep oranges, fiery reds, and finally dark purples and blacks at the bottom, creating a dramatic, apocalyptic atmosphere. The lighting is directional and high-contrast, coming from the upper left, casting bright highlights on her face, chest, and right side of her body, while the left side of her torso and legs fall into deep shadow. The rendering is highly polished with smooth gradients, airbrushed textures, and realistic anatomical proportions typical of high-end fantasy illustration, avoiding harsh brushstrokes in favor of seamless blending. The signature "Boris 92" is visible in purple text near the bottom right quadrant, along with a small "T" logo in the extreme bottom right corner. The composition is vertical, emphasizing he
