Okay guys, current bounties are listed in the opening topic! I'll keep it updated.
I'm starting a new reward system using what I call 'Dango Tickets'. Each is worth $10 USD, and you can exchange them for Steam games, Steam/itunes gift cards, or even a free physical copy of The K.E.Y.! You can earn Dango Tickets by submitting art fulfilling one of the bounties and approved by me, OR by referring a new contributor to The K.E.Y. who then submits approved contributions. That way, even those who aren't artistically inclined have a method & incentive to help the project!
Have fun ^_^
