A stunning mecha girl with flowing long black hair stands in an intense battle stance, her face set in determination, surrounded by fire embers and dynamic cinematic lighting. HDR and ultra high-detail showcase the intricate design of her mechanical armor, as bokeh and light bloom create a vivid atmosphere. The depth of field adds focus to her figure, captured in a style reminiscent of concept art crafted in Unreal Engine 5 with RTX technology for a photorealistic look. Despite the awe-inspiring detail, note the artistic choice of missing arms and hands, adding an element of intrigue to the scene, while maintaining an unapologetically fierce and powerful presence.
