Well good news for us is, Hot Toys is backing themself a bit into a corner with this bust, it's going to set the bar for a future 1/6 figure and if they don't hit it, there'll be a backlash. I'll get this bust, it looks fantastic.
More likely the $75 that Predator is, I think the $50 Rambo price will be for simpler designs like people, but the creature ones will be a bit more, but in the case of this ALIEN bust, I think it's worth it, looks great, doesn't have any screaming problems like the Predator one has.
I don't see the dog alien in it at all. It's a bad angle though, if you look at it quickly, those fins or whatever they stylized into the base up by his arms almost looks like it's supposed to be part of him. I'm glad the whole base is sculpted and artsy on this one though, much better than the ordinary black stuff like TDK and Rambo.
