I want to see your cels that are great not because 
they look beautiful, but because they represent 
some special moment for you.  These should be cels 
that a collector unfamiliar with the anime would 
look at and go, "eh!"   ^_^

Of course, you are required to explain why your 
cel is special to you.  ;-)

I just received a great example: 
The very first moment that Tenchi and Sakuya see 
each other!
