Animation Character Sketch

Hello all graphic monsters, designers and animators! :) We are a game development team, currently working on a Halloween game. We need a character, a madcap, daredevil boy/girl that will be dealing with sweets and playing tricks in the game. It could be probably a red-haired, freckled kid, 10-15 years old, looking very nasty, but without aggression or negativity. Please submit your very rough and basic sketches along with the bids and links to the previous animation/character works. Thanks a lot in advance and good luck with the bidding.
