How to use this prompt
Giant robots only feel giant when the frame gives the eye something human-sized to measure them against, so keep the 'tiny wrecked cars below' and shoot from a low angle — remove that reference and the mechs collapse to desktop-toy scale. Backlighting does the cinematic work: 'low orange sun' plus 'volumetric god rays through smoke' separates the two silhouettes from the rubble, which SDXL otherwise blends into one busy metal mess. If the mechs fuse together, add 'clear gap between the two mechs, distinct silhouettes'. Resist stacking more adjectives on the robots themselves — detail the light and smoke instead and the machines read cleaner.
Variations to try
- Night neon version — move the fight to a rain-soaked street at night lit by shattered neon signs, reflections on wet asphalt, cyberpunk magenta and cyan
- Aftermath version — a single victorious mech standing over a fallen rival in silence, dust settling, one searchlight cutting the smoke
