Not necessarily, though that may help.
You could link up the two animations pretty easily by adding a frame or two between when she's sitting and when she flies up. Otherwise, the wings/everything else could use movement (There's also a few unmoving pixels in the left wing, and her eyes don't blink properly.)
The part where she turns into a shadow could be either sped up, or you could drop a few frames. It's a bit too slow, though it looks nice.
