That reminds me on my school friend, when I first time saw her drawing a running horse and she was really good for that age. I was very jealous of her skills, your drawing is very good, like how you managed to show the muscles of a horse in motions :)
Thank you @stef1, I really like horses! I think steemit helps me to do art more often than I did before, finding free time is usually the biggest problem for me.
