I think it is important for the main characters to make an appearance in the piece finally. The completion of the piece will be based on the interaction of these five birds, how their gazes connect them, how the light plays on them, and how they hold their space. Right now, each is a little too strong, a little too much an addition, but they will become more subsumed into the piece as time goes by. After all, they exist in the space; the space doesn't exist for them.
