I agree^. Could also say the same with the archery range...
Some buildings are too far apart, also not much in upgrade size and lots of empty space.
To improve, I would add a second tier onto the building and make it bigger to fill up the empty corners. Also remove the water tower, it kinda random and doesn't fit in the stables setting- its not a farm.
Not saying it's a bad model, just needs more... The hay and water feed areas are a nice touch, would also like to see those expand with upgrades.
