Some nitpicks.

Trees should be further away form the structure. Otherwise it suggest that the estate is poorly maintained. Leaves and branches could fall directly on the roof.

Also, I am no architect and could be wrong but I thing the dormers should be aligned. It make more sense structurally to have a straight wooden beam instead of 2 halves, one for each side.
With the same logic, I would move the chimneys so they do not intersect with the wooden beams supporting the structure.


On the other topic, I am still using Photoshop CS6, which is getting pretty old by now. It was the last Photoshop you could actually own. I really dislike their new payment model, so I will have to find an alternative eventually. Some alternative would be the Gimp or Krita but I haven't seen a lot of maps on the latter.
Now the Adobe suite is even worst since they ended their partnership with Pantone. People have to pay even more is they want to use Pantone colours otherwise the only Pantone they can use is black.
