Create a vibrant, high-contrast portrait of a young woman with short, spiky hair and piercing blue eyes. She's dressed in a sleek black and silver costume, complete with a flowing cape and a bold, golden emblem on her chest. The background is a swirling vortex of colors, with dynamic text "UNLEASH THE POWER" in bold, graffiti-style font, with a metallic sheen. The camera settings should be set to a wide-angle lens with a shallow depth of field, emphasizing the subject's powerful stance. Incorporate a HDR Effect to enhance the colors and contrast. The artistic style should blend traditional comic book illustrations with a modern, digital twist.
