Thanks for all your kind comments!
@dandelO:
The terrain features in the last one are not my work, but nearly pure Mars (Hirise data from Gasa crater).
Concerning the atmospheres colour I took the freedom to show a clear day on Mars as I imagine it, the average day may be somewhere between your more pinkish version and my blue one. But i also like your bluer version.
And before I can make that movie Thebadger wants to see I have to kindly ask your Permission, dandelO, to use your planetary grass shader. That one has helped a lot for the terraformed mid distance images.
Even then, I am afraid I have to work in hospital for a living, and Mars is only a hobby.
Greetings from Mars,
