First of all, this is a photo. I drew the original piece with colored pencils and those never scan well. It's really a pity, it's fun to use them, but if I know that people will only see the piece online it's no use even trying to color with them.
Anyway, it's the sweet reunion scene from Tim Burton's Corpse Bride. If someone doesn't know, the dead guy is the boy's late grandfather and they're reunited when the dead decide to attend a wedding in the Land of the Living.
