Character. Scene. Feeling. Image. Artistic 
elements. Seiyuu :D Lots of things, really. I 
mean, one of my all time favorite cels, and 
Escaflowne pan cel, doesn't even have characters 
in it...I bought it for the incredibly detailed 
background of the Zaibach fortress (it's the 
Melef hangar :D). It's so absolutely gorgeous, 
you can't imagine...and, because I adore the 
Dragon Slayers melefs, and thus Alseides, with a 
passion, the fact that they're there helps :D But 
then, there's some of my Mikael and Raph cels, 
which I bought for scenes, for the happy squishy 
feelings I get looking at them ^^ And then 
there's my Toward the Terra cels, which I have 
because it's my all-time favorite anime. I could 
go on forever on the why and who and where...it's 
all about what I love, really.

Mmmm...squishy feelings :D
