Cels Forum

Hello,

Go to the bottom of the cels forum and in the 'title' field
of the search feature, type in 'key'. You will get some 
replies to that question which go into lots of detail.

However, I do not know what 'key lines' may be referring to...
unless it is in some way referring to the quality of the drawing,
or perhaps to a camera position drawn on the pencil..?

Best,
Ash

PS: Merry Christmas! Its the 24th here so maybe I'm early for
alot of people..:)
