I'm missing something. Coulda gone to MUFON, but no. What is the source of light atop the "alien's head" at the end? This is the first time I have heard of an alien carrying a light source around, much less shining it down on the top of its head. Lens flare ring seen in seg1, it's not hard to speculate that one can see legs under the light. And down-pointing light in seg2, my guess its a hiker with a headlamp, and the eye socket shadows are more pronounced due to the angle of the light.
