Something i have been working on for a few days now. Still has a few bugs but i should be able to release it soon.
Works really well on larger nature type images.

Result after running script with default settings.


At the moment the filter has 2 settings "Depth" and "Contrast" ideally it will also have a setting to control paint lines size and maybe neatness. Just a sneak peek.

interesting outcome
waiting for your script, Rod!
