Recently, I've shared the Pandorian springtime visual influencing aspect with you, even if it's not explored enough. 

However, it'd be perfectly contrast with Mangkwan surroundings. To be honest, they weren't disclosed enough for me in the last movie either, despite its long running time. That's why I believe to see them more, and I mean everything, but especially, their routine. Just as we met Omatikaya in the first film, we are supposed to get to know Mangkwan better. We, spectators, learned to "see" the positive characters 'cause they were always close to us. How can we see these damn Mangkwan killers if they're still far away? (I hope you understand what I mean - it's not about physical distance). 

BTW, this could be done, in particular, with a flashback to the Varang's past: show us their blooming forest before the fire (I still can't help but think how mesmerizing the falling petals would look in 3D). Plus, it would add another parallel to the "hypnotic" effect: first it was about something spring-like and alive (not necessarily positive, here we aren't talking about the level of kindness of the tribe, but about the level of beauty of their area), then - drugs, ash, AFAA, you know)

P. S.: Definitely unexpectable photo, even for me, and there will be "Part III", I guess

What about a Flowering period on Pandora? Part II
