Superheroine Sleek Form Fitting Outfit Deep Blue

Design an image featuring a superheroine with a sleek, form-fitting outfit in deep blue and silver. She should wear a streamlined mask that covers her eyes but leaves her mouth uncovered. The cape is long and dramatic, flowing behind her. Instead of a logo, incorporate a stylized symbol on her chest, resembling a star. The lower part of her costume should include high-waisted shorts with a matching belt, and knee-high boots. The setting is a dark urban alley illuminated by faint neon lights, creating a moody atmosphere. The character exudes confidence and strength.
