I have decided on my final edit, and now need to consider the layouts of the images on the pages in a book.
Thinking back to my original design idea, and after looking at the amount of landscape orientated images I have in comparison to portrait ones, I am now thinking that I should work with a landscape book, rather than my original portrait one; with more emphasis on the photos themselves, rather than smaller details which I was planning on adding.
I still like this design idea, though, so I will adapt this so that it works on an A4 landscape format instead.
