Wow, how did you do that? Very cool to compare in that way. The color shows all the gear (tack?) best.
It's a bit busy and tightly framed (ear) and as edited, the b&w has too many middle grays to be of interest for me; the elements kind of run together. I'd like to see a b&w with more contrast - perhaps really bring out the red in the horse in color, then in converting use the red filter to make the horse appear whiter. Other ways to accomplish also, of course.
