Medieval-Fantasy Themed BRB Sign

For this challenge I took the topic a bit differently - instead of building letters and then building around them, I decided to put the letters inside the build, literally. And so, here it is: A medieval-fantasy themed BRB sign.

First letter - The first B - is a small horse inclosure with a house on top (marked with reddish-brown wood around the building and the fence)

The second letter - R - is an old, yet still working gate, with holes, fallen collumn and overgrown walls (marked with dark-bluish gray accents on the gate)

The last letter - The second B - is an watchtower with balcony and a small stall with weapons (marked with right-most reddish-brown wooden pole and the additions - balcony and stall)
