Aww! Such a great picture! The colours and details are great.
If you're open to constructive criticism: Is the golden object on the side of the book a horseshoe? If it is, maybe do some research to see how they look. They don't have large circles at the bottoms and they have little openings so they can actually be attached to the horse. If not, perhaps make it clearer as to what it is?
But really, the size of the paragraph doesn't relate to how much it affects the image. It's barely noticeable, especially when the face has so much expression.
