No one's gonna kick your ass ^^ I'm just 
wondering if you used UV protectant glass, 
because light destroys cel lines and fades paint. 
You said you picked and matted carefully, so I'm 
assuming you used acid-free matting, but I never 
saw any mention of the glass. It's your choice 
what you do with your cels, just thought I'd 
mention it, just in case ^^
