A close-up of the face is dramatic and 
beautiful within the anime itself, most often 
because the shot has already been set up 
with a medium close-up or character 
establishing shot.

But, as far as cel-collecting goes, I like getting 
at least from the waist up because there is so 
much emotion that is captured in the body 
posture and the costume.

I mean, close-ups of faces don't actually have 
too much more detail than a medium close-
up, because, face it, anime faces are 
extremely simplified for ease of animation.  I 
mean, you don't have skin blemishes or small 
freckles and hairs or whatever else you are 
supposed to see in a real face.  You just get a 
big clean face.

So, to conclude my rambling, check out my 
Pompoko cel below.  If it had been a close-up 
of Gonta's face, I wouldn't have bought it 
because it would then be lacking those 
dangling little thingies on Gonta's pal (lower 
right)!
