Very good detailing. As she turns her eyes turn to maintain her gaze. very nice touch. And I note that the only thing in focus is the image in the mirror, mimicking how a camera would capture it. (Although Jiji, being so much closer to the glass, would be less noticeably blurry IMO. - Just a thought. I know it's hard to think of everything. (& Please - come and critique my animations because I'd respect your superior knowledge.))
I'm left wondering why her lips are moving, but presume you're capturing one of those moments when she is talking to Jiji. Oh - and I like it that she even *has* lips - as so any anime ignore them completely.
