So it's Akiko Kosaka (La Soldier, Moon Revenge, Tuxedo Mirage, etc.) Nice!
It must not have been that big of a deal if you didn't even notice it at first. I'd be much more worried over the weirdly-timed animation in that shot instead.
(Also, doesn't Riccardo Bacci trace over official art and shots, copy-paste Ikuko Itoh's faces onto them, and sell them on his own merchandise?)
