My god; some of these designs are a cross between ALIEN-Resurrection and the (unmade) Jurassic Park-4 (human dino hybrid) tier crap.
It's not that I wasn't happy with the final film, but too much effort went into trying to make PREDATOR "better". The cliché is true, if it isn't broke don't try to fix it. Just causes more problems and drains, time, money and resources that could've been allocated elsewhere.
The original creature design from PREDATOR (1987) to AVP-R (2008) (Wolf) was spot on, heck even Alec Gillis said, rival make-up studio, KNB EFX did a great job on PREDATORS (2010). Very noble they were professional in losing the contract to a more cost cutting studio.
Urgh these designs are shit and generic. Sorry. Would be ok as stock for a videogame, but a live-action movie?
EDIT. Also the last design has a very "PREDALIEN" look about it. Despite being vague, I really get the impression from the last AVP-GALAXY podcast that Alec Gillis and Tom Woodruff want to do an AVP3 as they hinted they are the "AVP-Prequel" that happens before ALIEN whereas "Ridley's vision/version of events" suggest a split canon.
