I've read that many folks who shell out big bucks for a T&S are disappointed that they can't get perfect shots right away. I understand it's a huge learning curve. I've seen lot of stellar images where the photog used just tilt or shift and then claimed that someday they'll learn to do both. Obviously it's not an easy lens to master. I do like your first shot a lot. Faux-Miniatures are ok once in a while, but they're gimmicky and get old after a bit. The real value in a T&S (IMHO) is the ability to have an enormous DoF all in crystal clear and sharp focus, like your first shot.
