Nice idea, but for me, it just doesn't seem clean enough. Also, if those things in cages are to be planets, I think if they appeared more solid it would give a better sense of it. The figure just doesn't seem clean enough, specially around the eyes.
The rules of three and thirds would have increased the impact of this image. That is, three planets, with the keeper moved slightly to the right and down a notch to give some movement and tension. As is, the composition is balanced and therefore static.
Nice work though, particularly on the eyes.
It looks ridiculous to me, but there's something I like about it too. I like the figure - the 'Alien', but not what's going around him (Assuming it's a he or if gender exists as all)
I am sorry to say but I just don't see a lot of photography in this one. I know it is expert editing, but it does say voters will rate based on the photographic nature and I don't see much. I am sorry but I can't rate this very high because I don't find the subject very interesting, or the photographic element to outweight the digital art.
