Very good looking strata, like them very much

Though I have some crits/comments on the overall appearance:
somehow you managed to get big differences in the coloring of your surfaces, which firstly is very nice but on the other hand a bit strange because the difference in lighting is somewhat big. I guess you're using quite some imageprojection techniques, like in your last image you've posted?
I don't really agree wit Kevin F about detail 1. For detail 1 it is still a bit noizy, maybe increasing AA would also help, but maybe it is also because of imageprojection.
If I am right about that of course

Another strong point is the hot looking atmosphere, nice work on the haze!
In overall still a very good image.
Oh and by the way....120 hours of rendering: I assume this has been rendered with TGTP2?
