Two themes present within "The Legend of Sleepy Hollow" are greed and gluttony.  The best character to illustrate those two themes is Ichabod Crane.  The guy is greedy to a fault.  He's a poor school teacher, so he doesn't have a lot of money.  That might be one reason why he is envious, but I have the feeling that Crane would be greedier even if he was the richest guy in town. Ichabod wants everything.  He wants food.  He wants money.  He wants the girl, and the only reason he wants her is because she's rich.  He's a very self-centered guy, which is surprising considering his profession.  As for gluttony, yes, Crane is a glutton.  He eats everything in sight and even fantasizes about eating.  For example, here is what he is thinking about when walking through a forest.   

"of dainty slapjacks, well buttered, and garnished with honey or treacle, by the delicate little dimpled hand of Katrina Van Tassel"

Wealth is another theme present in the story.  You could choose Crane to illustrate the antithesis of wealth and Baltus as the prime example of a character illustrating wealth.  Crane is skinny and poor.  Baltus is fat and rich. 

One last theme.  The power of the supernatural.  Use the Headless Horseman for this one.
