Science Fiction Light Blue Miniature City Winding Road Distant Mountains Book Cover Ideas with Cityscape Mountains Road Engineering Engineering Tools Glass Dome Urban Development Measurement Lines

A futuristic miniature cityscape is depicted in the center of the cover, appearing as though it's sitting inside a glass dome with intricate lines of engineering measurements around it. A winding road curves from the bottom of the cover, leading the viewer’s eye through the cityscape and towards the distant horizon where soft blue-gray mountains fade into the light, airy sky. Light blue gradients dominate the background, giving a sense of innovation and possibility. Subtle elements of engineering tools, like rulers and drafting compasses, are integrated into the design softly around the edges.

Fonts are modern and sans-serif, clean and professional. The title is written in uppercase with subtle spacing, in a light blue tone that complements the overall palette. Subtitles are italicized to give a futuristic and sleek feel, while structured organization maintains clarity.

The title is centered in the upper third of the cover, slightly overlapping the sky background but staying clear of the prominent cityscape. Below the title, the subtitle is placed in a smaller font. The road from the bottom edge directs the eye upward through the city and towards the mountains. Margins are balanced, leaving breathing space for the visual complexity.
