Mysterious Fiction Book Cover Design

My upcoming fiction novel needs a striking, professionally finished cover that immediately signals mystery. I picture a mood-setting landscape—fog-laden cliffs, shadowy forests, or any scenic visual that stirs intrigue—rather than character portraits or abstract graphics. Rich textures, carefully balanced typography, and a palette that whispers suspense will all play a role. Please handle the full wrap (front, spine, back) and supply an ebook-optimized version alongside print-ready files (300 dpi, CMYK, bleed included). The title treatment should remain editable; layered PSD or AI is ideal, with high-resolution JPEG/PNG exports for previews. Share a brief note on your concept, a timeline, and two or three portfolio pieces that show you can capture atmosphere through landscape imagery. I’ll provide the exact trim size, blurb, and barcode once we start, and we can refine via quick, collaborative rounds until the final cover nails that enigmatic pull I’m after.
