You know, I have the same camera as you but mine must be defective because it doesn't shoot anything nearly as good as this! :-) I really do like this one.
What great looks from the dogs. When "street shooting" you always get caught by the dogs and children. Adults are oblivious. This is an excellent example of that!
There is a story going on in this one. The tones are wonderful, great lighting. I think it may be the guy's back that brings this down a little for me. His stance feels very defensive like he doesn't want us to be involved in this scene.I get a kind of "blocked" feeling from this.
