I would said like, every cel I just saw posted 
under this thread would be my favourite. 
Especially those gorgeous Folken ones, and that 
movie Hitomi. *_*  Sadly, while Escaflowne is my 
favourite series, I only want to collect the 
nicest cels from it, and I can't afford the nice 
ones. ;_; So my collection sucks and my cels 
aren't very nice.  But, out of my personal 
collect, this is my favourite [it's also the first 
cel I bought].

however, if I ever find a cel of Van with his bow 
and arrow, or when he's practicing on the roof in 
Austoria and Allen confronts him and he turns to 
look at him with a crooked smile when Allen asks 
if he wants to practice with him . . . well . . . 
I'll sell my soul for those. *_*
