Blue Fantasy Book Cover Design (Evoking mystery and thriller)

Visuals: The cover showcases a tall detective man in a trench coat and fedora, alongside a shorter woman in a cloak. They are both standing in the foreground, facing a bustling steampunk city. Above the city skyline looms a shadowy, menacing figure. The city is a swirl of gears, smokestacks, and glowing blue lights, creating an atmosphere of intrigue. Fine, intricate ornaments edge the cover, enhancing the mystery.

Typography: The title "Quietus Arcanum Crimes Novel" is in a Gothic-style font with a slight metallic sheen, suggesting a blend of magic and machinery. The claim "Death lingers in the silence" is in a handwritten script, adding a personal, secretive touch. The author's name, Miguel Sabo, is in a bold, modern serif font.

Layout: The title sits prominently at the top center, with the claim "Death lingers in the silence" just below it, slightly off to the right. The detective and the woman are positioned slightly left of center in the lower half, with the city extending behind them. The menacing figure hovers in the upper right corner, subtly drawing attention yet not overwhelming the title. Author’s name is set at the bottom center of the cover.

Explanation: The visual composition blends steampunk and fantasy elements to convey the book’s mysterious and thrilling atmosphere, while the looming figure suggests danger and intrigue. The chosen Gothic-style font, with its mechanical and otherworldly resonance, ties into the book's fantasy and thriller elements, while the handwritten script for the claim adds a human, suspenseful touch. The matte paper offers a soft touch and subdued reflection, aligning with the story's dark and intricate theme, while spot gloss selectively highlights critical elements like the title and claim, making them pop against the steampunk cityscape.
