Mmmm, I like. The mane turned out nicely indeed, and the tail looks good curving like that. The pose is nice, too. While rather humanoid, it still works for our ponies with how selectively equine they are. I certainly love to see her smile, she seems to rather enjoy the book. Something tells me it's better than what the font of its title seems to reference. Also, nice tree there! Good use of whiter patches on the leaves/petals to make the canopy, and the purple lines denoting the unevenness of the trunk give it a nice colouration. Well done!
