3D compostions

When using after effects i added a sky image to a composition and the followed by 3 layers of images of sand, pyramids and a wall. The idea was so the camera looks like it looks over the wall so it can see all the pyramids so i had to add a camera to a new composition. the click layer new and then camera then i would change the angle of the camera so it lower this make it appear to be below the wall this is done by moving the axis. after the key frames are added in the cameras position you would then move up and gain a better view of the scenery of the sky the sand and the pyramids. So that i made the point of interest remained central and could reach the background i canted the view to the top which shows me where the cameras point of interest is. The reach is extended by grabbing x axis and pulling its reach to the background o fate sky.
