One of the oldest tricks to seeing your profile while snap shooting is by doing it in the mirror. That is great for working on your paintball game at home, but it doesn't give you that real deal feel!
When you head out to the field to do some snap shooting drills, try placing your camera on the edge of your bunker and between your bunker and the bunker with the target. Make sure the camera is facing you.
This will keep your phone out of harms way, and allow you to see the entire side of your bunker and all that you expose during your snap shots. Start off slow and work on profile, and then speed it up and work on speed.
