thanks for the comments :D
I know how you did all the others but I can't seem to figure out how you did that shadow on the moon 
I simply rendered out him singing infront of the camera, keyed out his eyes and made him a silhouette using a fill effect in after effects. Then i just played around with the opacity and stuff.
For the boxes I animated him singing in the spot where the box was, and covered everything else with green. So I he was basically looking through a green window. I then just layed the 2 on top of each other.
