His gums are looking very weird, I dont like that aspect at all, that gums are way too bright for some strange reason, it looks very distracting, and I almost focus only on that from the entire screenshot. It looks like that his teeth has been just recently added directly to this "mold" which evokes the impression of two badly joined parts. Im sorry but Im a perfectionist and these details bother me.
On the saliva from the poster, hair was used to straighten and even stretch the saliva itself, Im not joking, yes. . I noticed that right from the start. Its a weird thing, they should instead use a denser substance for it, but its not a big deal.
However these gums are pretty "off" to me. Even on the first photo, that gums are too different, almost "dry" on the first look, and brighter than the rest of his mouth parts. Now Im going back to the memories on the Xeno's from James Cameron, because they had and extra+ level of additional saliva inside their mouths, and that was awesome.
