I kind of think Pinhead is probably too obscure at this point. Those movies have been gone for a while and I don't think he quite reached the level of the other characters they've already used. Pennywise is hard to say, but he would be a hot choice out of the recent stuff. I could see licensing issues with the Stephen King, I don't recall any games connected to his properties other than Lawnmower Man way back on the SNES(?).
Agreed. I like Pinhead, it would be cool to see him in the game, but his series is pretty off the radar. A new one did come out last year, Judgment. It's up on Netflix.
I think she looks fine in motion, maybe they aged her up. Regardless it seems like most of the faces are going to change some since they're using real face models now. Skarlet looks great at least. NetherRealm clearly learned how to make slightly more grounded humans that look good effectively starting with MKX and really hit their stride with Injustice 2.
This is just going to be the reality for a little while, it seems most of the games with more realistic looking characters are switching to real people being scanned to use as character models. Capcom did the same with Resident Evil 7 and 2, and Devil May Cry 5. It's fine with new characters like Nero's mechanic, but jarring with old characters dramatically changing, like Chris or Claire Redfield, Trish, or Sonya.
I get it. Doesn't mean I like the change in her look, though.
