I need an image (photograph) redesigned

I have a jpeg that I have tried to use as a book cover but I cannot recreate the canvas as the background of the image is the sky. I need you to create the canvas and make the canvass color the natural layer of the background (the sky). The cover I have now is close in the color shade but I need the real sky so there is no contrast visible. I have Photoshop (and Gimp) but was unable to figure out the technique. The canvass/jpeg need to be extended 6x9 inches and the image placed like the current cover is. ## Deliverables I have attached the original image and the cover I made.....so you can see the issue/problem.
