book and e-book cover

This cover must work both as a thumbnail image for e-book distribution and for a book cover either 6 inches by nine inches or five and a half inches by eight and a half inches. The title is "SUNDAY IN THE PARK WITH GEORGE" Below that is a simple illustration of a green field with trees and a lake in the background and a man in security guard uniform with captain's bars on his shoulders or collar in the extreme foreground facing the lake or in profile. At the bottom is "A Novella by Francis Hamit".
