Mecha Standing in the Rain

Mecha anime key visual, detailed hard-surface panel lines, cel shading, dramatic rim light, sense of scale. A battered grey mecha standing still in heavy rain in a flooded city street, visor glowing red, water streaming off its armour. No text, no letters, no logos, no watermark.

Prompt tip: Describe the paint scheme in two colours to keep a mecha design readable.
