Sorry, i wasn't trying to drag you down, and force you to give that explanation to somebody else... My criticism was a constructive one, but if you don't trust me, at least see what other artists have to say about the issue i mentioned. And the reason i mentioned is because you spend time on something that could have been made without issues.
Get the book of Scott Robertson - How to Render - The Fundamentals of Light, Shadow and Reflectivity
He explains in detail the difference between a local light and Sun light and how to properly illustrate them in 2D.
Example of casting shadow from a local light:
For sure the scene in blender had the correct everything, but the light scenario from your illustration doesn't match it. And here is why: the way the shadows on your objects cast (represented with pink), point to a different light source than the light beam from the atmosphere you illustrated (represented with yellow).
Of course the light scenario from the examples i gave is a bit different than yours. A way to combine the two would have helped visually.
With that said, it will be the last time i will address someone on their creations if i spot an inconsistency.
