Crazy people - great concepts and renderings...

If that helps: a plugin for easily exporting SketchUp images, as shown in the viewport but with free input of height, width, format and compression.
Originally modified for a smooth scene animation to coincide with the Skindigo AnimationExport (Indigo Render Animation).
Here reduced to a SketchUp single image output with input of image parameters.
Transfer the code to an rb file called Single_Image_Export.rb and copy it to the plugin folder of the respective SUp version (tested up to SUp2022).
Restart SketchUp ....

Your penultimate picture reminds me of a landscape in my home country.
This is what it could look like there in 50 years...

I'm glad this helps.
I find it a shame that the SkerchUp programmers have not yet considered it necessary to implement a precisely definable image export, even though the basic functions are available in Rubi.
Regarding school: "Hochschule für Architektur- und Bauwesen Weimar" today "Bauhaus Universität" - we punched out punched cards and handed them over to the computer center (short time after Konrad Zuse...)
I learned most of Rubi from AntonS for scripting in MSPhysics and from customizing simple plugins for my own purposes. It's enough for small things...

Very well done
