Good, very good. 5th image staircase leading to the bridge, perhaps if you made a custom version of the double columns and give them a pitch of -1.57 you can use them to fill in the space between the ground and the bottom of the stairs?
As is I am hard pressed to understand why the builders decided to build that huge structure when they could have more easily leveled the land next to it and built a road. Perhaps you can flatten the left hand land bit and make waterfalls crashing down to the water. Break up the right hand bit of land, make it look like a chain of islands, in other words make it a reasonable project to build a massive structure like that to get somewhere.
8th image, the hallways where you are at ground level, perhaps increase the Z Offset - 100 to 300 should raise the camera a bit. While I understand the need to get a 'ground level' perspective, unfortunately the tiles and 'floors' usually look a wee bit off that close up. I note that the same issue applies to the first image I assume you have more going in and will figure out a wa to cover the blurred yuck of foreground road/rock.
Last image, the outer wall model. I am unfamiliar with it however its tinting slightly jars with the tinting of the arches and other building material. While it worked rather well as is as paving stone, as upright walls with the arches against it it looks wrong. Perhaps you can play with the walls tinting a tad to blend it in with the archways and other structures, or play with the tinting of the arches and other structural material to match better the exterior fortress walls.
since this is a cinematic I assume cameras will be panning and moving so I do not know if you need more stuff, environmental like grass, shrubs, shrooms, blah or if this is enough for the project. Mind while we have the chance to stare and pick apart these still images, in cinematic sequences the watcher will not pick up as readily the fine details and having a less cluttered image usually does work better, allows the viewer to focus on what the producer wants the focus on.
I look forward to seeing this cinematic when it comes out.
