Can be a little pedantic, here? Since a faraway star/sun seems visually small, people don't realise that it's not like a light bulb (point source of light). The star is millions of times bigger than the planets. So, it's actually a source of parallel rays of light (like the Sun). The light on the extreme left or right of our field of view is not radiating outward from the point source we perceive. It continues to be parallel.
Light from a tiny source vs a big object is like this: o < O Light from a huge source vs a small object is like this: O > o
It's one of the ways you can use to decide if the moon landing photos were faked -- are all the shadows parallel or do they radiate? [They weren't faked].
Hope this helps in developing future, [even more] awesome artwork.
Spent the last hour writing a comment lavishing praise upon and trying to find something constructive to say about every pore in the blasted landscape, but my mobile broadband hiccuped and ate it. I'm hopeful our descendants just might one day have the privilege of exploring our neighbouring stars - but for the time being communicating between two parts of Europe is enough of a capricious endeavour.
So before I drop offline again, will just say splendid work.
