well you can do anything for the Kenshin challenge, that can mean a post on Uesugi Kenshin, pretty much anything Gackt Kenshin related would do, even a review of his Kenshin DVD.

As for the costume challenge, you might pull some ideas from history, adapting something for the stage, you don't have to draw or manipulate Gackt, just a costume - and, the Wall Calendar prize is available to everyone who enters - not that you don't have a shot at winning the Desk Calendar.
