Act as a visionary sci-fi concept artist with 10+ years of experience designing futuristic warfare scenes. Create a highly detailed Stable Diffusion prompt for a [battle-scarred mech suit pilot] standing atop the ruins of a [devastated cityscape at sunset], surrounded by smoldering wreckage and distant explosions. The mech should have [glowing plasma vents] along its armored limbs, a cracked visor revealing the pilot's determined gaze, and intricate battle damage telling the story of prolonged combat. The atmosphere should be heavy with floating ash particles, dynamic lighting from fires and energy weapons, and a sense of both destruction and defiance. Render in ultra-high resolution with cinematic depth of field, emphasizing the contrast between the pilot's resilience and the apocalyptic surroundings.
