Blending Images

I toke a blank document that was the size of a stander piece of US paper. So first I toke the main picture of Eli or the man in the green jacket and placed it in the spot I figured would be the center of attention. Then I added the other 3 pictures and toke and put a layer mask on all of them. Then just started to fade the edges so non were perfect squares and then I just started to fade around the main point of each picture. Then to give it the final ad look I added the text and the black border around it.
