I generally like them. I think the DOF is a little too shallow on the robot eating the monkey's head. I love the 2nd one and the one of the tire. I want to like the one of the tree, but something about it just doesn't do it for me. The one with the hay bales is potentially interesting, but I'm not sure exactly what you want me to focus on.
You did a good job at showing and conveying mood and beautiful light. The massive oak tree at sunset and the windows in the old garage were my favorites.
