This is absolutely stunning. I really like how these ufos are flying in rank and file, the aliens must have very good discipline. The bright and glowing light at the bottom and the top gives this picture a somewhat lively atmosphere. But actually, the first thing that came into my mind when I've seen this picture was that it could also be a scene in an action game. The ufos might be floating platforms where you have to jump over to get to the other side of the chasm.
