I saw your plot and I like the terraformed part of it. I noticed that there was a water fall that went all the way down to a cave too, but it would have been nice if there was something of interest down there because it felt empty.
I like the first huge building that's in the main world as well, but I kinda wish that you did some interior work in it. The vast space within the building makes it seem so bleak. I'm unsure of what the building is used for since it has a lot of entrances on each side, but perhaps you can create a small hotel out of it?
Same thing goes for the town hall, there isn't much interior work in it besides the chairs and chests. It's like it's missing a room though. I think that it could use an extension because a town hall should have a large conversation area where people can "sit" and "listen" to whoever is talking at the meeting.
The wall design. It looks unfinished to me and I know that it's probably just a wall design and nothing more-- but maybe you can create some sort of garden surrounding that area and perhaps place the town hall within that wall design?
The light tower(?) I think that this build needs more contrast to it. It's full on stone-brick and I think that you can probably separate each level with just one layer of spruce stairs going around the exterior of the build. And maybe build a room or two within it as well.
As for the redstone work. I wanted to see how that moving duck worked, but I didn't. And the battleship game looked like a lot of work, but I'm not sure how to guage redstone builds so I'll just leave it at that.
I know that I may seem a little too critical and picky about certain things, but just remember that this is only my opinion and that you can choose to work with it or not. It doesn't really matter since I'm not here to vote on you
Good luck on your application!
