Interesting thread flow. The first two pages reminded me of trying to pin a live butterfly onto a display board with only two fingers of one hand..nigh impossible.
I have done something like this. And thus far I still find myself thinking things like "now, from X's POV A leads perfectly logically to B because X did her PhD about this particular alien civilisation and knows a fair bit about how they think. But the reader won't. How can I get enough stuff about the aliens in to make this work ?"
The obvious answer might be an encounter... right up front.
My pref is world building shown through dialog and action only, and any info dumps are limited to two paragraphs only. At that point it must be broken up with dialog or action again. Yep, YA convention.
Purely my rules and that style will not fit your style.All I can encourage you to do is to 'trust your readers' and let them participate in the world building. Their own imaginations will carry them a long way as you slowly release this fictional world on them. Choose your action scenes carefully so they reveal the most possible about the world organically and the same for the dialog.
You can tell my age here-- I see your style being more similar to a 'social-science' perspective of a Ringworld or Mote in God's Eye. I'd re-read those to see how they managed such technically complicated but highly successful sci fi books. Perhaps you can incorporate and apply some of their techniques into your own work.
The other major world builder is Dune, of course, but it takes an entirely different approach to presenting the world. Again highly different world that has been popular.
Softer yet would be Heinlein, Bradbury, and Norton, but I think you're aiming for something between the Niven/Pourelle and Herbert type style?
Keep us posted and best wishes!
edit...chose? sheez... can you tell client came in and pushed send? :-)
