Hey RorrKonn, I hope this is the thread you meant or else it will really be OT.   As for the illustrated look  in Garden Surprise first I used Topaz Clean https://www.topazlabs.com/clean to prepare it and then I used this filter forge effect https://www.filterforge.com/filters/11155.html  but I did more adjustments in saturation and overlayed and blurred selectively in Photo-paint.  I didn't really tweak the filter much and I didn't use the layer at 100% opacity either.   Mainly I just fiddled till I got the look I wanted.   I had a great method for illustrations and comics with the filters included in Photpaint and had even saved it as a script but forgot to backup all my custom scripts and nibs and when I upgraded my pc and re-installed  PP they were all gone.   Being too lazy to re-create it I just resorted to ready-made scripts so as you can see it's really quite simple now :)

Oh ya good thing it's simple ;)
I thought maybe custom shaders .
but I'm a fan of Topaz Labs,I've collected Clean & Detail so far.eventually I'll collect them all.

My back up's are scattered on multiple devices I know there some where,maybe but it's a lost cause to find them.
Good thing where organized ;) 

Thanks for the info.
