That way you get the eyes but also the added 
detail that a profile face shot usually gives (a 
full-frontal mug shot usually has a bland 
face/head element---only the eyes are detailed).

Overally, though, I'd rather collect cels from 
identifiable "moments" in the story.  If I want a 
nice portrait of a character, I'll spend $5-10 on 
a really detailed poster or scroll.  I collect 
cels to have pieces of memories.
