Also, consider the subject and mood you're going for. Before posing I find myself miming the desired pose or saying something or making some weird face to help me get in the mood I'm trying to convey. It's austistic as fuck but it works.
Also, since you're shooting giant monsters it helps to shoot outdoors so you can't scale it against something and pointing up gives the impression that the subject is bigger than it is.
