#3 would be good. I like the reflection in the window, good color and focus. I like the animal but the human subject throws it completely off. Maybe if he was wearing a straw hat and suspenders with a blade of wheat sticking out of his mouth and loose the glasses.....well you get the idea. If the guy wasn't in the picture at all it would've made it alot better.
I love the first one.
Number 2 could of been cropped a little.
And number 3, well there are so many things to look at, your eyes don't know where to look. But i do love the reflection in the window.
