This photo specifically caught my eye because i felt like it had the Matt Crump feel to it with the simplistic colour and use of reflection, much like the one i have taken off his website below.

 I then experimented in Photoshop with the use of different layouts and colour schemes, this is what i came out with below, i like the pattern that the mirrored photo gives however it changes colour when it crosses each border, it makes it look like one big photo.

This collage i thought went well together as the colours mix well and the way that the roof of the building flows helps you follow the 4 pictures with your eyes and compliments the photo in a nice manner .
