Book cover design for Charity coloring book - image coloring will be required

Design details: I am looking for someone to do a book cover to be uploaded to createspace.

It is for a charity coloring book, and the image on the front cover will need to be partially colored. The image on the back can be uncolored.

The book will be part of a series, and will have to follow the same style of having the name plate in the middle of the book. The example attached is still being edited, and whoever gets the job will get the name plate part provided with the correct info already included. It would also be a good idea to use a similar style of coloring, something that pops out at you.

I am looking for someone creative. There are 4 styles of images. You can run with one of them, or do 4 quadrants with a different style in each of them and the name plate sitting in the middle of the page. The color can start in the middle of the book and the edges blank, or something else. I'm interested in hearing YOUR ideas. I'm attaching 3 examples and not 4 as i cannot attach any more files.

Low quality images are attached. Much better quality will be provided to the person who takes on this job.

The final product should be done in illustrator, and any text should be fully editable.

I look forward to seeing your proposals and looking at any examples you might have.
Ideas for the visual style: See example1 file attached.
Preferred colors: See example1 file attached.
Where the design will be used: Createspace
