man, that's scary. Especially the lines on the Saturn-like planet. You see, i have this phobia of domes... This really brings it out: a planet and you can see the details. Cool picture, really goes to my very kidneys... Scares me very much. Congratulations.
I like the water idea, and the fog at the horizon. The image is very unique ( in a good way). I usualy like images that have to do w/space but this one has to be one of my favorites. :) good job! 10/10
