Eh...Needs to be 20% cooler.

Actually looking at it..
I think the body length is perfect. My arm fits nicely under her tummy for carrying and hugging.
The embroidered parts are perfect.
The rear legs are not as bad as they look in the photo. The chosen angle of the picture is pretty much worst case and the black background does not really help. Still, they could stand to be a little narrower or her flank a little fatter.
The Mane is an excellent idea on the top of her head, however it needs a little bit of reengineering. Its seems to prefer to lay backwards between her wings. I think putting a couple stitches on the biggest section of the red piece, straight through the orange piece to the top center of her head, would fix this while keeping the colors separate as they are. There are probably other ways, this is just one I thought of that wouldn't take much time or modification to the design.
