Painted Arch Optical Illusion Murals

A Midjourney prompt for optical illusion murals: trompe l'oeil fresco paintings of stone arches and steps opening onto deep landscapes, for wall murals, wallpaper prints and canvas decor. Pick the arch style, the view and two colours, and the arches frame a vista that runs back to one central vanishing point, so a flat wall seems to open out. Wide 16:9 with painted brushwork, from desert oases to alpine glaciers. A calm classical look that makes a small room feel bigger.
