As a landscape shot I think I like the second one better, the rolling hills and trees are just more interesting to me. However, the B&W does nothing for this picture IMHO. I'd like to see it in color like the first one
The second one has an interesting play of sunlight glancing over the hills. It looks like it would make a pretty decent desktop wallpaper to use at home.
I like the first one myself. I like that the subject is so far away and you can see him taking in the view as we do from a diff angle looking at the photo (If that makes sense.)#2 As said before would look so much better in color. # 3 doesn't really do anything for me.
