I'm showing my lack of knowledge, but when you state "transparent pattern 256", did you make a set of patterns or find them somewhere?

Hardy, your insects were done perfectly! I tried some ladybugs:

nicely done, Pat, and nice texture

Thank you, Dinasset.

Your ladybugs look right at home Pat!

on the subject, Gaussian blur 60x60 with the house masked off and cropped out
and saved to a new layer in the subject stack.
Then 64 iterations with a neutral color pattern on the blurred layer for a different look.
The saved house layer was ran through at 256 colors
with the same neutral pattern and then placed in the outcome.
The outcome size was the same in both runs and the position of the
house stayed in the same location which made simple alignment.

Thank you Animicule. I can't say enough about your images. How long does it take you to do an image? Sounds like you do a lot to them.

If this script has been updated, where is it? 47 pages is a lot to look through.

Thanks.

@animicule: IMHO that one is not the best source image to do all that procedural effort, the idea of letting emerge a central subject deserves better source images (sorry, but as well as I admire a lot of your outcomes I have to say also in this case the truth -my personal taste truth...)

@Pat: the elephant came out very well structured

Pat, the Elephant is a great outcome!
I do one or two per day at this time. I updated my home (recording) studio computer about a year ago to I7-4790K with 32G memory, win7, and running processor and memory with moderate overclock. If the image is total size 2300 the plugin run time is about 10-15 seconds with 256 colors. The large images say 8000-9000 total size may take 10-15 minutes at 256 color setting (but it runs in the background so I don't have to wait). Gimp itself doesn't appear to take full advantage of the processor, but G'Mic does. I do things a little at a time for a break from other things.

Dinassett, thank you for your critique! To my taste also I agree with you.

Thank you, Dinasset and Animicule for your comments. I try to improve. Animicule, I love your Sunnyfield.

great "sunnyfield", animicule

well structured, a bit too red (being a railway station)
what about this one?

Pat and Dinassett, both excellent railway stations!
Dinassett, how did you limit the red?

Here is an example of running Unsharp on subject to provide clarity.
Both were filtered with the same settings and layerstack.
11 colors on both, same pattern (neutral pattern).
Unsharp ran 2x on subject before filter.

re:Dinasset, how did you limit the red?

Just taken Pat's outcome and used selective desaturation on red color

One for fun!

Really nice, Animicule! So very colorful and precise.
