Never mind the suits, what's that enormous Easter Island head all about?
Could be related to one of the unanswered questions raised from the first film when they found the giant ship and that odd-look giant humanoid alien. My guess is that it's going to be the telling of the genesis of the Xenomorph created by that race, and that the giant head is some kind of artifact related to their culture.
I'm not one to be picky and get all pissy about production images, but I can see J-Mc's concern over that still. A lot can hinge on a film's overall aesthetic, especially when it comes to sci-fi. You want it to be grounded in modern-day thinking, not the camp B-movie style design of the 50's, which is now obsolete, that those costumes comes across as. If they are going to fuck about with that, it makes you wonder what else they are going to mess about with. The Devil is in the details.
See the suits in that are more akin to what we'd imagine what a space suit of the near future would be realistically like.
Anyway, it's just talk about design. Doesn't mean fuck all for what the overall film could turn out like, does it?
