How to use this prompt
The holographic face above the building is the detail that elevates this from a generic cityscape to a science fiction cover, and "colossal" is the word that gives it the scale that reads at thumbnail size. The lone figure on the rooftop ledge is the human anchor that stops the cover from being pure environment, and "in a long coat" is the genre signal for noir-influenced sci-fi. Rain-slicked streets reflecting neon is the lighting convention that adds the cyberpunk mood, and naming the three specific colours (midnight blue, magenta, cyan) prevents SDXL from inventing a muddy palette. The negative prompt's "cartoon, anime" ban is the backup that keeps the cover in the painted-realism zone rather than drifting toward stylised animation.
Variations to try
- Swap the holographic face for a massive orbiting ring station for a space-opera cover
- Recolour to amber and teal for a retro-futuristic palette while keeping the digital oil style
