Small, simple illustrations for a self published book.

Small, simple illustrations for a self published book of short stories. Illustrations will be used individually through the book, and blended together in a montage for the front cover. They need to be 1 or at the most 2 colour - probably line-work? Simple and expressive to work very small when on the front cover design with the others, as well as working larger on their own.
A selection of approx. six of the illustrations to be done initially and maybe some more later.

Please see the attached scans of the authors' (very simplistic by someone who can't draw). The writing around them is to help describe what is required.
