Hmm...

Well, I fully comprehend the arguments of @Dephicits; if it's a real moon (like some place you can get to) it'd never be perfectly square. No Perlin noise would create that.

So, @Dephicits: Do we agree on any of these (my responses are affirmative):

That the round moon has a brighter and better corona than the square one?
That the sun (either one) needs a brighter corona?
That the sun should be larger the moon in the sky?
That the moon (either) should definitely have phases?
