I love to draw horses. Mainly their head profiles. These are my two right now that i've done. My grandma has the one with the bridle hung up in her house and i'm giving the other one to my best friend for her b-day b/c she used to ride in england with me too.
But both of them bother me. I don't like the ears on either of them. And the first ones neck looks might tiny to me, lol. And it's eye. And the second one doesn't have that much detail.
You have very good solid basics , and are going to do quite well.
Keep it up. Just work on what you don't like, all artists can always do something better. I constantly have to work on things I don't get right !
Be proud of your drawings, and keep doing them.
