This is my go make me something project.  I made the little kids on the right look like they are flying the airplanes.  The side on the right represents the future and the right represents the present.  On the right you see the kids playing with the planes but, on the left you see them in the planes actually shooting at each other.  Also there are five kids roller blading on the right but on the left you see them fighting in a war.  I also extended some elements from the picture on the right into the picture onto the left to make it look like they are the same place just in different times.  The tree also extends into both pictures.
