Thanks, yes this can certainly be improved more.

Indeed. As I wrote in an earlier answer to you, how the Rim Wall is 
perceived from the ground is still a question to me. For the present image, 
I think I can do it by scaling differentially the semi-tranparant sky dome 
so that the Rim Wall lies outside of it. Hoping that no strange artefacts 
will appear in the process. In a future wip I shall experiment with media to 
simulate a proper atmosphere. That is going to be more tricky.
