She is beautiful! She looks very happy and the flow of the mane works wonderfully and adds greatly to the pictureThe shading is also very well done and gives Twilight more dimension than with no shading at all. I think the end of her tail looks a bit funny and maybe have more flow to it like with the mane. I also think a background, even a simple one, would look great. Overall you did a wonderful job and you definitely gave Twilight justice
