Sky Science Fiction Book Cover Design (Evoking simple, elegant, and educational)

The front cover features a serene blue sky with soft, fluffy white clouds. The title, "Performance Evaluation in the Organization," is centered against the blue sky, while intricate raindrop patterns cascade down delicately on both the left and right edges, creating a striking yet subtle design. A small cluster of golden gears, symbolizing strategic management, is arranged in the bottom right corner for a meaningful touch. Above these gears, a faint bar graph rendered in sleek and minimalist lines adds a layer of corporate sophistication. The back cover mirrors the soft blue and white tones while featuring a complementary arrangement of small golden gears in the lower third, anchoring the design.

Utilize modern, professional sans-serif typefaces like *Roboto* or *Montserrat*. The title is styled in bold but not overwhelming weights, in clean white font, with a subtle shadow to make it pop against the sky. The subtitle or tagline (if any) would feature a slightly lighter weight of the same font. The author's name is positioned subtly in smaller fonts at the bottom of the cover in a modest yet stylish way.

The design is clean and balanced, with the title prominently, but tastefully, aligned in the center. The raindrop details on both sides frame the cover without overpowering it. Supporting elements like gears and graphs are minimized in size and carefully positioned to retain simplicity. The back cover’s visual continuity is maintained as the golden gears create harmony with the front design.
