I think your stable is great meek75 - well done. Only thing I would say is that I'm not clear how a person would enter the small office - it feels like a door is missing. Also it feels like the wooden floor, desk and barrels in the office are a completely different colour to the wooden stalls and troughs, however that might be intentional to draw attention to the office or reflect different lighting?

I particularly like the main ground texture - super choice, and a great neutral colour that works very well with the stable stalls and hay.
