I choose a Comic book kind of feel for this Collage because I personally love comic books and have grown up with them so i thought it would be cool to attemp to create one.
A few of the minipulations i used for the text was the texture and stroke to give it an outline and that pixelated look. I also used the quick selection tool and made a mask of the big picture and the middle one of the three at the bottom so i could replace and mess with the backgrounds. I also put a black and white adjustment on the far right of the three small pics.
A new technique I learned while making this is how to import a new font to photoshop.
