I think the main difference is the old character model had a much rounder jawline. That she still has the chubby/round cheeks of the previous model makes the more angular jaw and chin all the more incongruous. For what it's worth, I much preferred the prior character model as well.
To everyone talking about Lexi and Kaylee's shape. I never lost their shape or the shape of any of the characters, I lost their material list. They have the same exact shape as before. No changes in jawlines, face, or body. The only change was their skins. I didn't document the original skins I had on them.
As for Lexi's face, it's probably just he angle of the shot, or it could be that I used expression smoother on this update. I'll see if that is causing a problem.
As for the short update, it's not much less images than what I used in v0.04, and not much fewer animations as well. I used more images per line this time with fewer reused images. The story just happened that way. I build and release updates based on image counts instead of word count.
