Hmm I rather like the first, its dark, creative and moody - however a litle think stands out is that I think a tiny bit more space above his head would have helped - it looks a little like you cut it off and is a little distracting. Other than that a good moody shot!
In the second two things stand out to me which damage the shot - firstly is the already mentioned blown out fur, its destroyed any detail and given very blasted look to things, might have been an effet you were after, but I think if it is you have gone a little over the top.
The other part is more situational and I appreciat that often its not easy to control such things (esp with animals as subjects) but the red and white shed/stable is really standing out against the background - its distracting to the main element of the shot I feel,
Overall I like your creativity, a few little nitpicks, but you appear to have sound method and ideas
