Hmmmmmm... I guess I really don't have a 
preference in that sense.  What I like in a cel is 
visible emotion, or humor, or drama, and I don't 
particularly care how much of the character has to 
be shown to express it.

Here's one of my all-time favorite cels, and you 
can't even see the character's face.  *grin*  I 
guess this would count as "full body"?
