A wonderful image, I like the colouring (and rendering) and the shapes of the landscape. Although I think you overdid the butt crack of that person. Looks like his/her middle riff imploded just a tad bit. And I think that with the use of such sharp edges it draws too much attention. A focal point. This is mainly a critique on the composition. Because I'm aware that this is a thing that's got to do rather with taste. I'm sure that you were very aware of this. For me overly focused body parts of space explorers is hardly relevant for my viewing experience. I guess one could argue that's it'ńs my own fault looking at that area, but I think that the suit in that area could've been toned down a bit. For the sake of the overall image, and not for some puritan ideals (which I don't share).
