Yello. Unfortunetly, I have a fair bit of criticism to give and scarce praise.
First of all, the map is pre loaded! This is a huge no no in map making as
(A) It shows very little effort has been put in and
(B) It makes for awful gameplay, as there is no actul development of how the game is played.
You could say that you created a single played world with a few houses, no?
I mean, I can see that you did put some work in, perhaps your just very inexperienced or you wanted that style but, compared to all the other maps your map lacks;

A theme (I know you said WW1 but really, if you hadnt told me I would never have guessed.
I just can't get over the fact that it is also multi biome (the result of a pre loaded world)
Lastly, I strongly suggest making a terraformed world, as a player may stumble upon a huge cave system, mid game.
All that being said, I appreciate the redstone work put in and I also think that if the houses were built with more "style" you could pass it off as a map. I can't see this map on MCSG (Just yet, I know it's a preview) but, with a lot more work, you might just be able to make it.
Sorry If I sound like a Inappropriate body part on a male but I'm just stating my honest opinion.
Best of luck,
