Nice stuff guys! It takes practice to get nice fluid shots. I'll go out in the field across the street from my house and use a whole battery doing orbital flights trying to keep myself in the center of the shot, maintaining the same distance, etc...
I sat out the other day and just let my P4 hover about 80 feet up for a shot including my house and the sky and just played with camera settings taking stills and short clips.
For composition I'll choose a subject and think about ways to film it. I'm working on a list of shots I'd like to try and get over the next couple of months. I've got a list of locations (all very local), subjects and ideas of how I want to capture them so I can go in with an idea of what I want and use my time and battery power most efficiently.
