I haven't seen it mentioned in the thread though it's explained in a lot of places, but this Predator is supposed to look a bit different because he's the runt of the litter, and was exiled by his clan. The plot of the film is him choosing to reclaim his honor and the acceptance of his clan by choosing the deadliest hunting grounds for his first hunt. I think he looks fine in 99% of the trailer shots we see, but of course every article picks the same thumbnail where it looks kind of awkward mid-roaring. You can also see more "normal" looking Predators in the trailer, so obviously the director didn't suddenly forget what their familiar look is supposed to be.
Also lots of people gatekeeping what a Predator is supposed to look like by showing the Jungle Hunter's face in the original Predator, ignoring the fact that almost every Predator looks way different in each movie : City Hunter looked very different already, then there was an entire new sub-species with the Berserker in Predators, then they had giant Predators in The Predator (but that one was pretty terrible for the most part), and then Feral Predator in Prey looked altogether very different again with a completely different facial structure. If anything, it's cool to explore a bit more about various clans or cultures on Yautja Prime (and the director of Prey and Badlands seems to be very invested in Predator lore).
