I'll dive in here. No one should sink to the bottom without a comment except me.
It looks like you live in a lovely area with great potential, and of these three shot, I like the third the most. They seem to suffer a bit from composition problems. For the most part, containg distracting elements (fence posts). I suggest initially shooting the photos with the subject off to the side a bit one way or another. Try to draw the viewer into the photo. Tell a story.
I do like the first shot too. But the centeredness and the fence post coming out of his elbow sort of detract from the feeling I get from it.
The third would be better if it didn't include the fence post in the front and maybe shot from a little lower angle to break up some of the lines.
