A very poor shot, I'm afraid. Motion blur from camera, colouring is weak and uninteresting. The horse appears friendly and gentle, rather than powerful and intimidating which is what your title implies. Has the feel of a snapshot entered in a hurry.
It's a little out of focus, and the background is too infocus, reduce your aperture and sort your focus out. Also, I can't find a link to the challenge.
Another picture which depends too much on the title to make sense. As it is, it's a fairly weak link to the topic at hand. His nose is also out of focus.
I don´t know what to say really... The quality of the shot is pretty bad, poor focus (or even no focus) bad colours and poor contrast makes it look very flat. Also I don´t see how this is supposedly "broken"? I gave it a 1, hope you do better next time.
