Digital artwork concept art depicting a fierce female ninja, clad in sleek armor, with the subtly etched Prompt Hero logo on her chest. The ninja is poised in a dynamic stance atop a rooftop, overlooking a sprawling dystopian cityscape shrouded in mystery. The setting is a dark stormy night, and the city is illuminated by sporadic, flickering neon lights. The composition is rendered in a vibrant comic style, with extremely intricate and detailed elements. Lightning occasionally punctuates the heavy clouds, casting ominous and dramatic lighting across the scene. Shot with a Hasselblad camera using long exposure techniques to capture the energy and movement, the atmosphere is one of intense anticipation and electrifying tension.
