My Pet Rock: Sky & Clouds [Updated]

This is a background for a scene when the rock is falling from the sky. The red rectangle represents the frame, I drew the clouds larger than this so that they can be moved or rotated slowly. I have updated this background, so that it uses manipulated cloud photos instead of Flash-drawn cartoon ones. This is  to make it inkeeping with the rest of the shots, and also I think it just looks nicer, as the first one was done very quickly.
