Love the colouring and terrain features in the last shot, Jan, looks really nice. Atmosphere maybe a little blue/dark, from what I've gathered from recent true-colour Mars imagary.
The crater I made isn't supposed to be a carbon copy of Victoria, by the way. I just used it as reference really to get an idea on diameter/depth/features on a real scaled terrain/atmo, which actually isn't correct at all if I think about it, since the planet still has an Earth radius! Never mind, still worked out fine for a night's tinkering.

And, ahhh, of course your atmosphere is blue, I'm forgetting the title of this thread.
