Very nice cel.

As for modifying the cel images, IMHO, do what 
you want with the image.  It's your gallery.  You 
decide how you want to display your collection.

The only problem I could ever see with modifying 
the image, is if you ever decide to sell the any 
of the cels with modified images.  This is 
because of obvious  reasons, as I am sure you are 
well aware of.

As for myself, a good share of my cels have had 
some sort of clean up work done to them, as my 
scanner quite often, browns the outside edge of 
the cel.  Also for some reason, I am a firm 
believer, with my cels, not to remove stuck 
sketches, as to prevent from damaging the cel in 
the process.  I know there are several ways not 
to damage the cel, but, it's not worth it to me.  
So I remove the sketch in my scans to make the 
cel less cluttered, and more distinct.  Case in 
point, my new Sarah cel.  All those sketch lines 
made the cel to "busy".
