I hate quoting, so I'll just list each assessment:
-I mostly mean that there shouldn't be any visual of the alien following them back to the ship. The audience should be smart enough to figure out that the same one that later appears on the ship was the same one from the derelict. Have it emerge from the darkness of the engine room or something for it's first moments seen on the ship.
-Yeah, the rhino part would do best to be cut. Doesn't exactly seem like what they would consider "worthy prey" anyways.
-Main reason I think the Pred should be downed by a human, the neautral party, is because in AvP stories it seems like the Alien always has to be the one to perform the fatal blow in the WWE battle.. this just causes one fanbase to get all pissy, and I think a human being the one to bring the Predator to the point of arming the wrist-bomb would silence those who would complain. Sacrificing a "climactic" fight between the two species, that would just seem like fan-masturbation, honestly.
-I never saw AvP (the movie) as getting it right in any way. Only way
personally think a Predator or Alien should fight is through a kind of cause and effect/cat and mouse game. To me, close quarters combat between the two end of looking awkward and degrading for
both.
-Understood.
-Already mentioned the Alien's entrance, as you had alluded to it going through the exhaust- that's a great idea. But personally, for the Predator, I think it could be cool to see it maybe override a maintainence airlock's control. I just thing it getting in through a hatch in the roof (which is supposed to withstand the vacuum of space) is a bit awkward. With the overridden airlock, he could get past the airlock and shut it once inside. I loved your idea of hiding in a lower room of the ship to clean the trophies, and that could still easily work, and in an undetected manner.
Jesus, to tell the truth this makes me want to do my own AvP project.
I'm not even sure if I'm getting this right, but I definitely think this would be a great way to give satisfaction to fans of both franchises. A single Alien.. and a single Predator. Awesome. Of course now I have a lot of anticipation for this, and I'm only trying to help. If you want any more suggestions, just mention it.
