Although it's near impossible for me to pick 
one favorite cel, right now I'm going to pick this 
OVA cel of Hotohori. It's the best OVA cel I've 
ever come across of him, and Hotohori, when 
I began cel collecting, was the first character 
who I had ever wanted a cel of. Needless to 
say I was very happy when I received him. :)
