Hey there, I noticed a slight asymmetry of the Canine head when using the ft_f_default facetype. To show this, I used a blank character and snapped a small spot mask to above the mouth and mirrored it. Then, I compared the position of the spots with ft_f_default set to 0 and to 1.
As it might be hard to discern above, I overlayed both pictures, and as you can see, when going from one facetype to the other, the spots don't spread out symmetrically. Notice how the right spots are closer together than the left ones.
Now I don't know if this is a problem with the head itself, the face type, or maybe has to do with snapping masks to the surface and then mirroring them, but something is definitely off.
And here is how I noticed, I had the feeling that this character had a slight stroke or something
