Awareness Poster "Food can be your biggest enemy"

I should start by saying that, bring my ideas to Photoshop is not easy, I say it before I am saying it again. Every tip you think I should have used, or advice would be greatly appreciate it, as I am trying to do a better job.

My only trouble with getting ready this picture was that apple, I wanted everybody to be able to see the apple as well as the bomb, blend it together was not easy... Full opacity with normal blend mode was not pretty looking at all, so I changed it to full Opacity but with "vivid light" blend mode which made the bomb a little transparent but still well defined, This way I could a blend the apple color with the bomb a little bit better. I also decide to use the healing brush and play with the colors and contrast. Following you can see the pictures that I've used for this Poster.
