Hi Bart,
Are you the Campbell who got my book as a gift?
You have a good wife having such nice ideas. I really hope that you were not disappointed with the book!
This is a very good dio Bart!
I had a bit of problems interpreting the scene as the germans look a bit to relaxed for a surrender. Are they driving themselves also?
Do you have a ref. picture for the house?
The thing who caught my eyes are the satirs.I see two problems with them. They float a bit above the board walk, that's thje first an easy one.
They also are (IMO ) to high. That could pass , but they lack a protection on the left and right side of the upper stair. There is defintely a risk of falling high.
You did probably run into a layout dilema i was in myself also a few times
The lack of space and some calculation mistakes lead to a problem to get stairs
done correctly. I understand you very well.
If you like to redo it I think you have to options here.
I don't know if you are copying an original house. The best would probably be to replace the door and redo it longer (with perhaps a glass part in the upper part of the door) and replace the stair with only two steps. (around 5-6 mm height each)
If you do not want to remake the door, you may also try to do a stair like this one (can't find the words, so here is a pic of one of mine)

with the steps going all around. (perhaps rounded) You would not need the railing but they still would be to high probably.
A lot of talk about this tiny part of the dio, but as the rest looks very good, this one hits me.
The wall near the railway could use some more weathering. On top of it and running down.
Sincere congratulations on the scratchbuild and welcome to the club!
