Great idea and I love what you did with it! Although the textured off-white color definitely works, I'm curious about what it would look like in another color. Very cool design! I definitely think you could sell it in some capacity beyond this contest!
Take a look at mine if you want at [link] - thanks!
I love this design - best one submitted so far! And don't worry that Saturn has no solid surface - more than likely there would have been floating hotels and cities orbiting close to the rings (what a view!) or even perhaps through Saturn's main 'body' of gas!
