London Through the Eye of a Designer - Book

I just started to put things together for my research book; I struggled a lot at first, there are a lot of pictures of all different sizes and shapes which makes it quite awkward.  I think were I went wrong is because I took it for granted that I could just put stuff in and sort of arranging around as I went along but that clearly did not work.

Those spreads look all over the place; but although I had a grid I still struggled with the captions, quotes, text...

I spent a bit of time designing the grid; as well as master pages for chapters.  I need to figure out how to put 2 page numbers in one page; I'm afraid so far I've been unsuccessful.
