The smokey atmosphere is great. Usually a planet seen through the sky will be lighter than its surrounding space but you did a great job going the other way and really using it to add depth. The scene has such a warm colour palette that it's easy to forget it's a hundred degree's below freezing
Very cool stuff, from what I know Titans haze is actually too thick to allow view of Saturn in visible wavelengths, but uniform orange sky would be kinda boring. Has something Alien-esque to it. Great work!
