Eastern State Penitentiary Montage

I had to create a montage from three separate images. So I recently took a trip to the Eastern State Penitentiary and really enjoyed myself. I took multiple photos of the exterior walls from different angles and decided to use those. My idea was to create a image combining three views. So i had two pictures from the corner looking down one direction of the wall and one from the other. I also had a picture of one of the towers. The final product has sort of a two point perspective. It seems like you are standing at the corner of the building and both sides recede back in space. I used many tools in photoshop to create this effect. Including blur, erase, smudge, crop, lasso and free transform. I used blur, smudge and erase to blend the images together. The others I used to match the sizes and shapes to fit together.
