Hi, is there anyone who experimenting with Daz Studio to make characters on CTA2?

I've been experimenting using Daz Studio, render the t-pose image and got .png files.

The image results from Daz Studio can become very smooth or rough depends on the render settings.

The problem arise when I'm trying "cartoonize" the characters before it's ready to be deployed on CTA2.

Does anyone knows how to "cartoonize" any photos to become CTA-like-characters?
The similar samples of the raw images may looks like on this url:

Cheers.

PS:
I'm using photoshop ATNs that I've bought from a certain site to convert the photos, still working on it.
