After Style J, this is a "variazione sul tema" as used in the classical music period : it also makes use of G'mic Engrave as main function.
I wanted to create a look approaching Van Gogh style.
At the moment - pour s'amuser - in the filter there is an option to have 3 levels of the effect:
- weak, medium and strong.
Here an example, using a Deviant Art image.

weak


medium


strong


As usually, I asked my friend Issabella to perform tests to find out errors and give suggestions during this WIP period

Thank you so much Dinasset for letting me play with this awesome filter.
I post here my very first outcomes.
To treat with portraits, I've used mask = touchup final and the gray hue according to the intensity of the effect.

Here I haven't used masks.

No masks used.

No masks used

Continuing my tests. I love most of the Van Gogh results

Wow, great carousel, Issabella.
And you took also the risk of applying it to portraits, hehehe....

Thank you so much Dinasset, I'll try more on portraits.
I see such similar looks to Van Gogh's style that I'm really excited about this filter.

The little cat is for Pat.

No bad, IMO

You are the hidden grand-daughter of Van Gogh!
Also the portraits look good in spite of the difficult task of softening the texture.
Great job!

My first attempt to play with a portrait.

My second attempt (D.A.).

Third attempt (D.A.).
But this time taking the risk to preserve much of the strokes visibility.

...or, with a more yellow-ish look.

You are brave, Dinasset. I like your results.
