Editing the Carrie's War photograph in photoshop: back cover

After taking my photos for the book cover, I decided to play around with the levels and the hue/ saturation to try and get it looking how I would like. I wanted the definition between the layers to be more clear and I also wanted to warm the image up a bit to make it look like it had more of an orange glow, rather than a bright one, I also straightened it up. Im really pleased with how this has turned out but the real challenge for me now is to work out how i'm going to insert the blurb and barcode into the image so it still looks good. Here are the images before and after they have been edited.
