Act as a cyberpunk concept artist with 10 years of experience in dystopian world-building. Create a highly detailed MidJourney image prompt featuring a [stealthy female assassin] clad in [sleek, form-fitting nanofiber armor] with glowing [neon-blue circuit patterns]. She stands in a [rain-soaked alley] in a futuristic megacity, bathed in the flickering glow of [holographic advertisements] and [neon signs in kanji]. Her [monochromatic visor] hides her eyes, reflecting the chaotic urban sprawl. Include subtle details like [dripping water from a fire escape], [smoke rising from a nearby vent], and [a discarded energy weapon] at her feet. The atmosphere should evoke [loneliness and high-tech danger], with a color palette dominated by [electric purples, deep blues, and toxic greens]. Use cinematic lighting to highlight her [silhouette against the neon backdrop].
