Galaxies Fantasy Book Cover Design (Evoking sombre, mystérieux, and magique)

Visuals: The cover is divided symmetrically down the middle. The left side is dark, with a brunette girl shown from behind, her hair cascading down her back. The right side is bright, featuring a blonde girl also seen from behind. Stars and galaxies swirl above them, with the upper rim of a large planet visible at the bottom, stretching across the cover's width.

Typography: The title "SHAM" is bold and positioned at the top center in a mystical, serif font that conveys fantasy. "Sous l'emprise de l'Autre" is in smaller, elegant script beneath it. The author's name, Ruby Neige, is at the bottom in a simple, contrasting sans-serif style.

Layout: The symmetrical layout places equal visual weight on both sides, with the girls acting as focal points. The planet and celestial elements link the halves. Text elements are centrally aligned for balance.

Explanation: The visual composition capitalizes on the theme of duality with its symmetrical design, using light and dark contrasts to embody the mysterious and magical elements of the fantasy genre. The placement of galaxies and stars on top links the two sides, suggesting a shared sky, while the planet's presence at the bottom grounds the design, creating an expansive universe for the narrative. For typography, a serif font lends an air of mystery with its ornate style, suited to a fantasy novel, while the script for the subtitle adds a touch of elegance, emphasizing the storyline's intrigue. The choice of materials, specifically matte lamination, serves to deepen the fantasy atmosphere by reducing glare and enhancing the interplay of dark and light hues, making the cover visually engaging and tactilely satisfying, aligning beautifully with the book's mood and genre.
