Goat is correct about the framing. Seldom is the center of the frame the best place for the subject. Especially things that are moving (the duck), and yes the dog. As Goat says, empty space can be used to your advantage. And I'd agree on #14 being the best though I'd personally prefer it cropped tighter across the top. I don't like how the top of the pond runs through the very center. I wouldn't want to see the bottom cropped at all as the reflection is very nice. I think it's a good photo, but I really think there's an even better photo inside there. Experiment with different cropping to bring it out.
For framing I've found it useful to pay attention to how scenes are framed in well made films. They usually frame them just as you would want to frame a photograph.
My opinions only. I'm no critic.
