Similar comments to your advanced Pig Farm model. This may not be massively-different, but it's interesting & different enough, says I, to be a good addition. More importantly, the changes all look fitting (except perhaps for the below) to in-game, which is most important to me. All in all it's a great alternative/expanded Barracks, so good work!
My only possible qualm (not nearly as big/definite as for the Pig Farm) is those posts that ring the lower level of the barracks... They look sharp & cool, but it's like, the different color wood is a bit... off? Or off-putting. Like, it looks weird next to the other color of wood present in the stakes around the outer edge. Could they be made the same color (i.e. texture)?
