A change in my Central Image?

There is a possibility of changing the central image for my front cover since I have noticed that it looks quite similar to my double page spread. As you can see, the two pictures look quite similar; this may be problematic since I do not want the two pictures to look the same.

I might change the central image of my magazine cover to this picture instead:

 

I think that this image may be suitable for my front cover since it does not look similar to the double page spread. However, there may be some implications with changing the cover image because it will take more time to adjust, which is not beneficial since I still have to work on my contents  page. In addition, I may not end up using the image which means it will waste time and effort. It is not certain yet if I am changing the front cover, but it is just a possibility.
