You know, this reminds me of buying a new TV. It's easy to see which picture
you prefer when you're looking at a wall of different sets, but when you get
yours home, it's the best picture because there's nothing to compare it to. :-D
I'm late to the game here but from a photographic standpoint, I like #4 best. Compositionally and technically, I think it puts your subject into the foreground with more strength than the previous three. The shallow depth of field helps accomplish this nicely.
I cant get all technical about composition, but I like #3 because the one on the left is more in focus....but I'd sample some from all 4 ....just to be a fair judge
