Wow. Those were two very impressive AMVs.
I'm particularly floored by the second one because it captures Shiori's instability and malice. The song goes from being somewhere between melancholy and sweet and then dives into harshness and frustration. It even managed to take the symbology that surrounds Shiori and put it to good use. Like when the bird hits the window.

Also I just had an OMG moment when I realized just how similar the frames where Wakaba lets out a tear from having her letter to Saionji read and later when she is given the leaf carved out of wood are.
