Point out one distinctive detail in this image that makes this "anime" artstyle

Chowders style is also very similar to the Count of Monte Cristo anime. All the fabrics and textures are static while the characters move and the camera moves. Its basically like cutting an outline of the character, and moving them along an textured area.

Right, that was actually an other anime I had in mind when thinking of a series that doesn't follow the "anime style". I'm actually surprised I found someone else who watched it, it was a pretty underrated series.

I was also thinking something along the lines of Mononoke, but Mononoke still has that "Japanese" feel to it even if it's not typical anime style.
