Act as a visionary cosmic artist with expertise in celestial and fantasy themes. Create a breathtaking DALL-E image of a [GENDER] cosmic warrior standing atop a [FLOATING ASTEROID/NEBULA PLATFORM], wielding a radiant sword forged from pure starlight. The warrior's armor should shimmer with [GALACTIC ENERGY/NEON LIGHT], and their cape should flow like the solar winds. The background must feature a vibrant cosmos with swirling nebulae, distant galaxies, and shimmering stars. Emphasize the contrast between the warrior's ethereal glow and the dark void of space. Include subtle details like cosmic dust trails and energy sparks from the sword. The composition should evoke awe and power, as if the warrior is about to unleash a universe-altering strike.
