I kinda of wish that the left side wasn't so blurry/out of focus - I can see the interest with regard to patterns and the flow of the fur and veins over the body and muscles - but that blurry patch distracts me from that.
I'd also say that it doesn't speak "horse" to me. A horsey person might see the horse more clearly, but this doesn't shout "horse" to me - it shouts patterns and animal.
