Yann, I apologize if it is bad protocol to post 
this picture, but I thought it would be useful 
for comparison.  I captured it from ebay.  Delete 
this if you want.  

The highlights in the circled area (especially 
the lower right highlight) look wrong to me when 
I turn down the brightness and contrast on my 
TV.  And it may be my imagination, but the path 
and the turn the shadow/light line takes on her 
left wrist doesn't look quite right.  

The original ebay seller had a French email and 
the high bidder was in the US, so I'm not clear 
what this cel is doing in the UK...
