Now that I started terraining again myself, I will comment in the terraining section more again instead of only looking.
So you will get the first comment for now
If I take a look at the development of this terrain, I have to say that this went through some major changes. While in the first screenshot your tower looked a bit more medieval or ancient. The latest tower now looks steampunkish in a way (thanks to pyra's models, which you mostly used very nice, too)
I really like how you created building like things out of it.
But even though the technique is mostly nice, the changes are not fully positive in my opinion, by placing more and more things, the terrain lost in points of atmosphere. The lonely tower with the bridge could have so much atmosphere in it, that was lost by adding all the things around, mainly the buildings. The rocks would have been a nice addition if they would have been placed without the "buildings" on them. But by those, the atmosphere is kinda destroyed in my opinion. Even though the background idea is nice and you stated you like it, you could add a lot more to it, remember the glow model from utm is your friend to create a custom sky that looks more interesting and could improve the atmosphere of this terrain a lot. And hell, atmosphere is what this terrain is about!
Keep it up!
