My point was not to say, Dutch Tilting the camera a lot is always to a bad effect. It can be a great effect if used wisely with purpose.
A general rule of thumb could be: Don't make the flat ground look too slanted, unless it works for a certain effect.
Here, I am posting a photo with nearly the same amount of tilt as your last post. I avoided showng the ground, and trees often do grow diagonally, so it looks buildings are usually straight up, unless they are pyramids, broken down structures from destruction, or the Leaning Tower in Italy.
