I think the pictures themselves are decent, id prefer it if you pp the first two a bit, the colors aren't too great and im guessing you were shooting at around noon, which would explain the overexposure. The dog/wolf picture is good, nice crispness, my main problem is the background, its very distracting whatever that is to the left of his right eye. I'd have prefer to seen it both at a different angle then that, since that is pretty much bending over angle.
