Book cover: split diagonally, top shows teenagers in a school hallway, bottom shows a tour bus, instruments, and masks on a beach at sunset.

Professional book cover for a Young Adult novel, vertical format. The design is diagonally split by a dynamic rip from top-left to bottom-right. Top-left half (School world): A crowded school hallway during recess, blurry students walking around, in the center 8 teenagers stand invisible in matching black hoodies, with sharp details like colorful bracelets on one wrist. Triste grey and blue tones. Bottom-right half (Band world): A warm, hopeful Danish sunset at the beach with a matte black tour bus decorated with glowing fairy lights. On the sand lie music instruments (keyboard, violin, clarinet, electric guitar), an open notebook with drumsticks, and 8 glowing neon face masks (yellow lightning, gold, deep purple) lying together as a community. At the very top, large title: "THE ECHO MASK". At the bottom, subtitle: "SUCH NACH DEINER STIMME" (bold print). Below it, author name: "E.L.D." in fine white handwritten signature style. Voir plus
