Yeah, I think it does. Really nice! I'd agree with @NessIllustration regarding the size of the horse compared to the human.
One area I would possibly adjust is the curve in the back leg, where it juts back and then down. (How's that for trying to describe horse anatomy.) I think yours is anatomically-correct, but it's possible it may read just a bit better if it's exaggerated a bit. Yours kind of comes down gradually to that point, where it could be more of a definite curve. Something like this image.
Kind of a minor thing really, but it's just something I noticed.
