I have a juniper tree here. It's going on the other side of a boulder, that is present in my background image, but when I place the tree it appears to be in front of the boulder because of arrangement. If I could crop out a straight line on the bottom 25% it would look more accurate. As I type this out I wonder if I could use the clone tool on the boulder before I place the juniper, clone the boulder to the side, place the juniper, then move the clone back...might be a work around.
