Film Establishing Shot

An issue which came about when creating this establishing shot was cutting around the debris in the shot. It was simply that it had many rough edges which took a lot of time to carefully trace around, however, I overcame this issue by going over it a couple of times. Furthermore, another issue which I faced was placing the Moon and Earth behind the mask of the debris. For some reason, after effects wouldn't allow me to do this. After several changes to settings and the order of the layers I was able to make this change. It was likely to have been a glitch in the software.
