CGI Backgrounds (Personal Work)

Scope of work
Creation of CGI Background from scratch.

Description
I wanted to use some Blender features, notably Geometry Nodes and Volumetric Lights and this is what I came up with, overall I'm quite satisfied with how this turned out in a days work!
Everything in these renders is pure Blender output, no touch ups whatsoever, apart from this subtle bell curve to boost contrast.
