A few more images, courtesy of my daughter, who used a disposable camera but then scanned the shots that came out:
Sensei, Clairellen in her beautiful Hazuki (Tsukuyomi Moon Phase) outfit, Valpalla, and my Liz at Slugfest East. Sensei's whiskers (enhanced by natural real black facial hair dye) look especially dashing here.
Sensei as da Count, Liz as Black Chii, and a group of admirers, mainly friends Liz met as part of the Binghamton or Yale Anime Clubs. (She doesn't go to Yale but lives on the campus, so she's accepted there as "a non-weird townie").
I thought the blue ears came out especially well in this shot.
