You're on a roll with prizes at that other site, congratulations.
Separating the woman from the props, she is a very nice looking model--face nicely morphed, busty but not implausibly so, good figure, excellent texture, nicely detailed. I myself don't find any incongruity in the props/outfit combination, as everyone knows and expects that people in the future and people from outer space have a fashion sense that's very different from contemporary trends of Western culture. Plus other elements like the lighting of the scene, etc are all good.
The only thing I do find a bit puzzling about the image is the perspective, as it (deceptively no doubt) appears that she is standing at a 45 degree angle in relation to the floor. Did you employ an unusually short focal length on your camera lens for this scene?
