This is pretty amazing especially for a camera phone. Honestly can't find the words to describe the photo in itself, the movement and everything was captured perfectly.
Actually I have already seen it a few time but it always was inside a big hall. So the ground was even and without hills. And I wasn't as close as you seemed to be. But it still was impressive how fast and agile they were. But I would love to see it outside with hills and water and all that.
