The first step was to isolate the guy on the motorcycle. I used the threshold to get the basic shape and then the layer mask to try and clean up the edges. A close look at the high res will show that I didn't do a very good job.
I added a high school football stadium in the background to give it some context. I couldn't find one with people in it taked from ground level so I settled for this one.
For the final product I added some lettering to the wood and played with the shadows under the clothes pins. I also added the reflection of the motorcycle tires in the second bus window.
