#1 is very interesting. How did you see it ?
#3 is a classic eye pleaser, like it very much.
#2 is a problem, not with you but with the subject. I think I know why you took this shot (maybe). I am looking at such a entrances all the time and to the eye they seem romantic and worth a shot, but it doesn't work too often this way on the picture. In this case "it's not you, it's the camera" !
