A book cover design with title: "Les Murmures du passé". The cover should feature a renaissance-style high school building in the background. In the foreground, there are five girls: the rebellious one with black hair and green tips, and green eyes; the popular one with blonde hair and blue eyes; the studious one with brown hair and brown eyes; the cool one with black hair and black eyes. The fifth girl is a Ghost, wearing chic 1990 clothing, appearing slightly translucent. They are all depicted as if investigating something mysterious. The color palette include dark, moody tones with hints of silver and blue. The title is in a gothic font at the top. With the autor's name: " Sombiniaina J." At the bottom. I want a cartoon style.
