Whew! Yeah, long time.

I don't know how you're doing these but the last 4 skies look very good if I
ignore the color noise.

If you could monochrome the most intense colors that might help.

Hmm yes, what I thought. That may give trouble when integrated into a 
landscape scene with trees and such.

I don't understand.

I want to give up...
I posted the fruit too early... I just tested the cloud shape and it is hard to
control. And too much work (includes reducing the render time) in the future.

And we want you to continue ;)

"Hard to control" is just a pessimist's way of saying "something
encouraging to toy around with".

As for the render times, I gather that this whole thing is a stand-alone
program, right? So maybe it would be worth trying to port this to OpenCL
and get your graphics card to do the job. I reckon the computations
should lend themselves to the architecture of GPUs.

That said, if you decide to cease work on it, maybe you could publish
the source code under some free-ish license, so that others could pick
up on it. From what I see, it has a lot of potential that would be a
pity to waste.

I was thinking of post-processing filter, too, like was mentioned before. I
don't know how possible that is though. Idea being, desaturate colors that go
beyond a certain threshold since the overall colors of the sky isn't fully one
color or the other.

Of course, that still would show a kind of colorless noise. The ideal thing
would be to duplicate nearby colors and replace the intense red, green and blue
colors with those. Yet again I don't know the limitations to such filter
creation. Just was thinking out loud.

GPU is an unfamiliar field to me.

That's a good idea but the code is ugly currently(ew). If I decide to cease
work, I will publish it that time

I got it. That is something like the median filter. Well
