I think all these issues could be fixed with more photos.
The Farm House:
The house is situated off to the right-hand side of the picture, if you had shifted the whole mission to the right, the mangled gable would look fine. The edges of a 3D model never have as much detail as the middle, try to get the subject in the centre of the mission.
The Old Factory:
This looks like it could have been shot at a lower altitude.
The cylindrical tank would benefit from some shots taken a low orbit. This can be done separate from the mission and uploaded with the rest of the photos.
The same goes for the chimney, narrow objects such as towers, posts, chimneys etc. need more attention, so more shots taken from closer and especially from orbits, would help.
