A fierce cyberpunk street samurai with neon cyan hair streaked with electric pink, standing on a rain-slicked rooftop in a neon-drenched megacity at night, expressive fierce crimson eyes with detailed neon sign reflections, cel-shaded with bold black outlines, dynamic diagonal composition with falling raindrops, deep midnight purple and electric cyan pink palette with neon glow, rebellious urban mood, scattered holographic advertisement particles and distant flying car light trails, cyberpunk concept art with soft bokeh of distant holographic billboards
