See if you can find some cels from the same 
sequence in online galleries, etc for color 
references, because the colors are generally more 
different on video than they are in comparison to 
other cels.  (Usually a lot darker on screen than 
the cel actually is, I find)

Oh, and if you need a certain ep/movie from a 
series, there's probably a 90% chance I have it, 
and higher that I can get it and put it on my ftp 
so you can download it if you have a decent 
connection.  

=P  I'm totally against people who sell fanart as 
real cels, I even offer rebates to people who bid 
first and ask questions later on my fan cels, 
even when they're obviously marked as 'original 
art' 'hand painted by me' etc all over the 
place.  It's just, y'know, not a nice thing to 
do.
