Yeah, that's what Yann said. But at the same time 
I am seeing contradictory stuff on other sites, 
and it's a bit confusing. I understand the 
concept of layout and clean-up sketches, and knew 
these were what these are...but I also considered 
them genga as well. Kind of one of those "one 
item can be more than one thing" type of 
scenarios...I had never been told genga had to be 
a completed sketch. Does a douga have to be a 
complete item? Not necissarily, it can be a 
floating mouth, so I don't understand why a genga 
cannot be a floating mouth. Most of the cel 
collectors I have talked to consider any 
production drawing other than the douga a genga, 
however I can understand that layouts are 
different, since they are not neccisarily 
sketches of the characters as much as planning 
out the scene. Right now I'm still trying to nail 
down the definition of genga taking the words 
from several people, Japanese and American 
collectors alike...but it seems that everyone has 
such radically different definitions (I mean, the 
impression of "if it's not a douga, it's a genga" 
seems to be shared by many people, including a 
few of the Japanese I've consulted...so it's all 
kind of a thing to interpret). I suppose it 
depends on how much attention to detail one 
pays...
