The idea with the magic is that she summons a ball carrying other balls and sends them out. I started with her T posing like in your edit, but I felt it looked too samey compared to the rest, and crossing gives her a bit more flavor IMO. I do agree her moving her arms back is a little too smooth compared to her torso, so I'll either make it snappier, or make the body a bit more fluid in that part.
I think I'll work on reworking the magic altogether. It's not really what I had envisioned, and the animation changed along the way, too.
