Ooohhh, I dont know, I went to Akon, and the hand 
painted fan cels that were shown at auction went 
for LOADS of money.  Make a simple background for 
her, and buy a nice frame at like, Walmart, and 
people will jump all over it!  I saw fancels go 
for hundreds of dollars at Akon, and they were 
pretty run of the mill fancels.  I think the fans 
really appreciate the effort, so they are willing 
to pay quite nicely :)  Unlike my poor art, that 
went for piddles because it was digital :(:::  Oh 
well, hope you do well!
