Art Style - Possible Comprimise

After some thought and fiddling around with the Toon Shader in Unity, I am beginning to think that the Japanese painting style may take up way too much time or might not be possible within Unity. Although apparently its possible to script the Shader to work in a particular fashion, once again this may take too much time and might be too difficult with some of the models.

The alternate Art style I propose however would still be 'toony' but not to the point of outlines, rather the amount of detail could be limited instead along with the textures and colors. Noticeably lesser poly models could be implemented to also emulate this as well.
