Hints:
-Blur amount: applied as first step, if desired. It's a median blur.
-Sketch amount: gives a bit of relevance to some pieces of the image contours
-Posterize: it's a component of the process to flatten a bit the areas
-Chroma amount: as the word says, adds a bit of chroma
-Ageing amount: gives to the outcome a look of an old painting
-Frame amount: extend the minimum fuzzy frame always applied (% of the image)
-C2G amount: used to give one of 3 different final looks (if not 0) using the next parameter:
-C2G layer mode:
. -LUMINANCE=adds a light contrast
. -DODGE=creates a sort of a "sketch on white" (common for aquarels)
. -BURN=adding strength to the colours
-Sketch on top: reinforces the "sketch" look of the outcome
