vintorix,

You're certainly welcome to your opinion. 

A couple of things I had to consider before coming up with my opinion:

In most cases, the script solution was being sought because I was dealing with 30 fps, and a day or two per frame in that case was out of the question. That filtered look might work for some people, depending on the context. For that human touch the filter-solution wasn't acceptable and the compromise was hand rotoscoping on 3's. It lowers the motion resolution but looks more hand drawn because it is.

Currently, as comics or storyboards, I don't have to concern myself with that kind of motion but still have a significant number of frames to push through. Simplifying the style would help that a lot. But then I'm also using 3D as a way of getting all the rich details of well defined texture maps and don't want to lose the work there. Clearly, if I'm after a more graphic appearance it will require some style choices that will be a balance of processes. 

Back to Mark's initial comment, making a 3D image painterly, you have to consider whose style are we talking about? Rembrandt or Wyeth, et al.
