Wow, I love this one. It reminds me of the illustrations of a storybook I had (which was in English, so it was ages before I could actually read it ): "The Unicorn and the Sea", by Fiona Moody. Have you ever heard of it? The resemblance is so striking, especially the soft colours and the horse! I love its dapple coat and the very strong hooves, and the characteristic face.
Hey Jenny, thank you! I was going for an old story book vibe. I haven't heard of that book but I googled it- there isn't much on it but I saw the front cover on Amazon. I see what you mean! I would have liked to see more illustrations... Anyway, thanks for the kind words
