Follow-up activity for Once and Future King Fine Arts Activity...?

In the Humanities cl that I teach, we're reading The Once and Future King by T.H. White, and i had my students do a Fine Arts activity. They had to do something fine arts-related on one of the characters in the first few chapters of the Sword in the Stone (Wart, Sir Ector, Merlyin, Kay...). They could do some sort of creative writing on one of them, they could write/compose a song, or they could draw their portrayal of that character (hand-drawn, with oil pastels, computer-generated, with colored pencils, etc..) and I dont know what to do for a follow up activity. Since the beginning of the book seems to lag a bit, I want to do something fun to get them interested in it. Any suggestions?
