Exploding picture

This is my attempt at the exploding picture on photoshop. I don't think it looks very good because I wasn't in class when the teacher was showing the class so I had to try and follow a routable clip. I spent a lot of time with the paint brush because I think thats what gives it the exploding look.
I forgot to take screenshots of my work in progress and couldn't go back to it because the work itself took an hour. IThis is the youtube clip I used but I got confused a quarter of the way through the video and done my own thing.
