Well, I find them...mildly disturbing, rather then ugly, especially the non-big nose villager face.... are immensely ugly, oh yes. Same applies to ghast and slime faces.
They all (except the female farmer and the witch) are not original, i.e. did not exist in the last version of this TP released by John Smith himself. In my opinion, they don't match the spirit of this texture pack at all, which is why simply deleting them from the pack is my first cosmetic change after downloading a new version. I only leave the farmer and witch textures in the /mob/villager folder.
