Ok, I'm not english but I try my best to explain. Something like chests, or a fireplace or a time for the miners to rest- nothing big, or a stack of the mined ores that are mooved on the surface or webs^^ or any kind of boxes, as you use conquest there are so many boxes^^ or a whater thing- I don't know the word atm... maybe gravel or some kind of dirt... that's what I call the microdeco :-) I hope I could explain at least something that I had in mind.

Wow really cool build! You should keep making more of these maybe like different sizes ^_^
