Sword-Wielding Spherical Mecha

On a ruined battlefield dyed in dark teal twilight, a girl wearing a dark gray mechanical suit stands confidently with a greatsword in each hand. Behind her, a massive spherical mecha hovers surrounded by orange flames, with dual circular cannons at the front of the sphere glowing red, heralding overwhelming firepower. The girl's red eyes reflect the battlefield flames while revealing cold battle resolve, and her short brown hair scatters in the storm. Red and orange sensor lights throughout the suit signal combat mode activation, while battle scars etched into the armor panels at shoulders and chest speak of veteran experience. Shattered structures and debris scattered at her feet show the aftermath of fierce battle, while orange clouds and smoke in the background blur the boundary between sunset and war. A post-apocalyptic illustration capturing an overwhelming, dramatic moment of the girl warrior standing before the spherical mecha, rendered in dark teal, burning orange, and gunmetal gray battlefield colors.
