So, of late, a lot of layout/genga sheets have 
hit my hands. Most are, if at all 
possible, "complete", having storyboard layout 
sheets, colored pencil douga, and black/blue 
douga.

Some, however, do not.

So, the question, in the first part, is this: Is 
it "wrong" to try to complete a set-up, by 
reassembling all the scattered pieces, or am I 
just being arrogant/greedy/a (insert word of 
choice)? If not, is it okay to approach people 
who have other parts of something you have, to 
try and make that completion?

I mean, I really like having it "all", when it 
comes to scenes or shots. To me it is like 
separating a cel from its background, sketches, 
&c. 

Secondly, related, is the same question for 
sequences. There are a couple of short, powerful 
scenes that I would dearly love to reassemble in 
order. Short stuff, maybe only 12 to 18 cels. 
What about those? Is it hoarding/greed again, or 
just an unhealthy desire to spend all my money?
