Act as a visionary sci-fi concept artist with 10+ years of experience in mecha design. Create a hyper-detailed, cinematic DALL-E image of a [COLOSSAL MECH WARRIOR] standing triumphantly on a [POST-APOCALYPTIC BATTLEFIELD] at dusk. The mech should have [GLOWING NEON ACCENTS] along its armored plating, wielding a massive [PLASMA GREATSWORD] crackling with energy. The battlefield is littered with smoldering wreckage of enemy drones, and the sky is filled with ominous storm clouds pierced by streaks of orange sunlight. Render the scene with dramatic lighting, ultra-high detail, and a sense of scale that emphasizes the mech's towering presence. Use a color palette dominated by deep blues, fiery oranges, and electric purples to evoke a futuristic yet gritty atmosphere.
