Ok, the two cels you posted are very, VERY 
obviously repros, and I'd hope painted from a 
screencapture (because that's the only thing I 
can think of that would excuse such horrible 
washed-out color matching when the paint job is 
decent) but *ahem*  it would also be likely that 
this cel was made from yours because it's just so 
close.  It's pretty easy to blank out colors on 
any outlined drawing so probably moreso for a cel 
and turn it into an outline with a mask tool on a 
computer so it might have been done with a 
photocopier,  (the lines are also really thin, 
thinner than I can manage with a paint pen.)  
They're also a bit darker on your cel, which 
would go along with what happens to outlines when 
you blank them out on a computer. But I'm not 
*quite* sure, because I've never gone the photo 
copier route before.

No opinion on the Urd one though ^_^  I'm a lot 
better at telling which is the copy than a spot-
on difference.  Her skin tone looks a little off, 
but that could all be lighting
