I was always told (and I've read the same) to keep the things in the picture moving towards it's center. "To give them space to move". Keep eyes looking inside and so on. Yet I often find myself doing quite the contrary and feeling justified in doing so.
Here, I want to illustrate "departure". Leaving. The expectancy, that in the next two seconds that plane has already left my frame.
For me, that plane in the left side would have told much less, that it does in the right end.
Of course, I could be all wrong.
But who cares? :D
