Since you took the time to "make" or "find" 2 UFOs, why not get them really focused? A bit blurred yes, but this is just too much. I see nothing of real interest in this picture. I like the line left behind them, but even that is barely noticeable.
I like the idea, but something is missing to make this look real (or fake real -- you know what I mean). Without a background there is no sense of scale to show that this is not a flashlight or streetlight, or other normal object.
