Children's Book for Halloween

I need 11 illustrations for a children's Halloween book. The book has two stories that can be read forward or backward, most of the background illustrations remain the same, however, main characters change. This may result in less work for you. In total there are 11 illustrations. Illustrations must be dark and gloomy, with a scary atmosphere. Characters include an older man and a dog and also a younger man and a puppy. Please bid in both black and white and full colour and provide examples of your work. This is an independent project.
