Duchess Illustration

I have drawn a nice picture of the foal from my story, The Horse From the Woods. This is the foal from the prologue, Duchess. Do you think that I describe her enough to get this picture in your mind? If not, please tell me how I could improve.

The Horse From the Woods: Chapter 1 Part 2/4

With the full moon above them, Natalie and Duchess rode down the long unpaved path, only taking a short time to reach their destination. Duchess quickly galloped the entire trip under the moonlight without slowing in speed, or growing in exhaustion leading Natalie to wonder where she had received this stunning endurance. Duchess’s movement was smooth and balanced, making it easy for her rider to stay on. Natalie grasped onto the reigns of her horse tightly however, in nervousness as she thought of never returning to her past life.
