You got the colours spot on, I agree this could do bit a bit of softening (surfaces/atmo) for perception of depth. Looks very promising.

Next version.  Yes, that is a huge canyon I know ;D.

The world is round... so you have to use spherical projection.

Oh, I like it.  I want another.   ;D
So this is Disney World.  Can we live here?

woah....thats HUGE!!!....

how high is the canyon to see it from this far??....the colors are spot on....

The canyon has a displacement of 5000 meters.

QuoteWell, the only thing I really don't like about this one is the polar cap. It just doesn't seem natural, too white (or perhaps, too sharp).
It's not too sharp, just too...I'm not sure how to say it. It's not too sharp, because if it were fuzzier it would end up blending too much with the other terrain. The problem is that its features aren't big enough, so it ends up looking like granulated sugar. The real martian ice caps have much larger features:

The rest of your terrain is excellent, though. Like you say it's the ice cap that needs tweaking.
QuoteNext version.
This version is better, but I still think it needs to have larger features.

You know what's worse than not being able to do anything right or make anything good? Not being able to blame it on anyone but yourself.

That's a good idea. For some reason I didn't even think of doing that. I'll see what I can do.

Woah!

Thats one nice render!

Good work!

I've been trying to get a good looking ice cap for my ice planet care to share your secret?

There isn't really any secret. In this image, the ice cap is made by using two surface layers. The first surface layer is slope restricted to 40 degrees. I turned the coverage down and changed the fractal feature scale to something like 500000 or so, played with the roughness and contrast, and changed the noise type to billows. In the first surface layer I turned the fuzzy zone softness down to about 0.5 and the fractal breakup to 0.9 or 1. The color of the first surface layer was a light grey (not quite white because you don't want to reflect too much light). The second surface layer is similar to the first layer except the factal is larger, perlin, and the color is a darker grey with low roughness and a contrast high enough to make the color show well. Just to add some interest instead of pure white. I can upload the tgc later if doesn't help at all  ;D.

First off, beautiful, wonderful picture.  Looks really believable.  Second, that is a damn huge canyon.

Whoa! Whoa!
Only possible problem i see is that the rest of the terain continues inside the valey. It would be a bit more realistic if the terain would change adruptly.
