Hi all!
There are very valuable comments here! Thanks a lot!
To add some food to the discussion, here is the document I based my dio on:

It seems the first "problem" for some is the left bank which is parallel to the plate. Well, I made this on purpose since I want to add a second plate later to reproduce the entire E shape dispersal. This way the "seam" will be less pronounced later. I plan to make several 54 X 54 cm plates and assemble them later to depict a small part of a British RAF WW2 aerodrome, with control tower, Nissen Huts, Barracks, vehicles, figures... and planes of course. So this is only a small part of a much bigger project (don't expect it to be finished until the year 2023).

You are all right, the open space on the right, behind the bank, needs something. I don't want to put a tree there for the reasons Derek exposed. I don't think they would have left a tree in the middle of an airfield, even if the dispersal is not near the runway. Marc Toillié of Mark58 said that sometimes a small barrack was placed there, Hmmm... I thought of a windsock but the location would be a little odd, even if it would look nice. There is also the possibility to put a warning sign (no trepassing bla bla bla...).
Another "problem" is the size of the dispersal. While mine may be a little undersized, I don't think fighter dispersal pens of this shape were that much bigger. If you look at the document above, there is not much space neither. I think the planes must have been pushed backwards in the dispersals. The banks are a little too short in my diorama though. I placed a Spitfire to compare with the Typhoon which isn't a small plane...

Derek, this will represent the sunny side of England!
My dislikes are the tufts. I don't know if they look right and realistic. I think they are a little "artificial". It's very hard to put them randomly. Hats off to the diorama builders who achieve realistic and natural looking grounds. I have a lot to learn here! I also don't like the gaps between the walls and the concrete. I will have to fill them in a way or another.
Oh well! It won't be perfect but I will try to make the best out of it. Thanks again for your constructive comments...
