I believe there to be many strengths in the montage, but I will focus on a few that I will keep in mind as inspiration for montage in the future. First thing being the photos ability to tell a story. I believe this to be very effective and powerful. The other strength of the photograph were its strong visuals and complexity. So many different aspects to the image allow the viewer to take time and analysis what is being presented.

Multiple focal points and a narrative have drawn you to this image and will help with the idea you have in mind for your montage.
