Fab, modern image for book cover needed!

C'est ce qu'une entreprise en/au(x) United Kingdom recherchait pour leur book cover design

I am after a unique illustration for a book cover to be designed, in a similar vein to this one. I particularly love the image. It's a simple drawing but is arresting. The main character looks mischievous and the science images on the glasses is a lovely touch.

My main character is called Mary Brown and she's very mischievous, chaotic, always getting herself into scrapes. She's also overweight and always trying to lose it, but then she sees a donut and she can't help herself. She's adorable, attractive, very funny and has loads of friends. When she goes camping she accidentally takes a kite instead of a tent and gets arrested while dressed as a nun on a hen night.
I need to somehow gather all that in a simple image like this on a book cover. I really want it to be an original image. Is anyone up for the challenge? Voir plus
