I'm becoming increasingly a "paper, not plastic"
collector, as I find that gengas have a real
impact that doesn't always come across onto the
cels.  I think it has to do with the fact that a
real artist is taking a stick and slashing it
across a piece of paper, magically taking a scene
in his or her imagination and making it visible. 
I know nothing about Samurai Deeper Kyo, but I
find your gengas very impressive.

However, my wishlist item isn't anything so
dramatic: it's just an irresistible Kero-chan from
the introduction to the "Kero-chan no Omakase" or
"Leave It to Kero" segment of CCS.  He's just
starting the "yachi" in "Konyanyachi-waaaaa!!!"
