Speedy matte concept

The first motive is stunning but really earth like.
The second is quite more spacy. I like the small guy in the middle and his shaddow. For me the blue lightning is too much and the athmosphere is to empty....maybe add a little bit snow.
The last one reminds me of Stargate and the sky completely fits to the scene. The foreground is a too empty for me. Add something for the story of the picture, maybe a man standing on a rock, or the peak of another Pyramid.
All in all I choose the middle one too call it my favourite
