Hi again Falcon
Alright, here it comes..
Ok, i think you need to create a real storyboard first as of every action and sequence you will "shoot" in the film. That way you got better control of what you gotta do, how long each sequence lasts and and focal depth and so on.. all the necessary info for each single shot helps alot to have. But i'm sure you're working on that now.
1st pic: This is interesting, good camera angle and lotsa visible sea with a pretty architecture. But what i don't like so much is the centered sun.. offset that a little to not fall into the normal CG trap of centering everything

and also some vines, flowers and trees should be in the scene as people live and work there. Markets could also be a good thing to have in the scene.
2nd pic: Not much i can say about this..
3rd pic: Good looking model there, but i can't really say much more about this one.
4th pic: This is about the same as the 3rd pic, only a bit more detail and meshes in it so i can't really say much about it.
5th pic: I like the texture on the mountain in the back, it makes the scene complete very well as it's like weathered cracked and shatted rocks smoothed out by heavy rainstorms in past million years until civilization set it's foot down by the mountain.
6th pic: Same comment goes for this as for the 5th image, the rock is pretty good and works well with the rest of the model. However there's one thing i do like to see and it's that the structures would show signs of wear and tear such as shattered parts, parts missing and small parts laying around here and there from the structures as gravity took care of it and it fell down
7th pic: Texture looks pretty good so far in this but really too early to say..
8th pic: This is the same as above just a different angle, so same comments as went for the earlier images goes for this one too.
9th pic: This one i like, especially the weathering and green dripping stuff on the structures makes it real, very good Falcon! i was hopeing you would add weathering texturewise on this too, it brings the scene to life.
10th pic: Well water is a issue as we all know already.. but a mideterranian look to the water would be nice

like the same colorscheme. Bridgecolums are so big they should be visible quite far down in the water, depending on the depth ofcourse. And also algea grows up along the stones of those bridgecolums as they're set in water. Also same should probably be valid for the rocks where the water meet the mountain
11th pic: Higher polycount on the mountain wouldn't be totally wrong
12th pic: Same comment on this and 11th pic as i gave on the 10th pic.
13th pic: And same comments on this too as i gave u on the 10th pic.
Well hehe that's all for now

i'm sure i missed something but i'll give you more indepth comments if you want to on specific things.
