this is awesome. great use of scale to show the size of this area...the navi vs predator thing sounds like an equally awesome idea. as long as their dimensions are right. the predator are about 7 feet tall and the navi around ten. that concept sounds like something i'd look forward to seeing.
Oh gee, what can I come up with with no sleep? Hmm...
Well I haven't seen Avatar (yes I hate those blue people that much) so I don't know how far their "ferngully magic" goes with the trees... I kinda had an idea that the Navi could use her influences to entangle him in the vines for a moment - No I don't just want to see Pred bondage! Whatever gave you that idea? - but I don't think they go that far in avatar. *Shrug* All I know is that their hair does a lot of weird, unnatural things and they can connect with the forest like people go online.
You could always have a high action chase scene through different parts of the forest, maybe take a ride on those red pterodactyl things I saw in the previews. Maybe have some local fauna get in between their battle, heating things up a bit if you really want to drag it out/add that much to it.
I dont think that making a chase sequence would be a good idea, that would just make the series longer that it should. I just need a couple of "action" scenes where the Pred is kicking her ass and two or three last paintings and thats it... is just that I cant think about good action scenes... bah
