Inspired and amazed by your work, I decided to try a challenging project myself.
My first 'grown up' dio will be of a WWI trench onto which crash landed a plane.
I know, it is a chellenging subject, but it is some time now that I think of it and I could not start with something else.
Now, I forgot to say that it will be 1:48 and that I'll ask you a lot of advice even though I tried to study your work in advance.
Since there will be a plane crash landed, the trench section will be maybe a bit longer than in real life, also there will be an observation post so that the trnch will not be that narrow allowing better view of the dio itself.
I started with the 'north' dich:




In this on I could not resist to try a little of earth patter: used ground coffee...

Here is a detail of the contenment wall and of a section of barbed wire I am planning to use later.

And here a detail of the corrugated iron (still not finished) that I am planning to use later...

This is it for the moment!
Please feel free to add any comment: they are most welcome!
