portraiture assignment

I'm thinking of doing the portrait photograph using water as reference to its symbolism in Judaism. There are tons of examples of why water is so significant for Judaism for ritual purposes and in everyday life. Water can be used for blessings as well as in punishment. The Mikvah is a pool of natural rain water used for ritual purification purposes for men, women, and even utensils. There are many examples in the Bible where water plays a significant role (Noah and the Ark, Moses and the splitting of the Red Sea...just to name some). Even washing one's hands is very important for certain instances (before eating bread, waking up in the morning, etc.). So what I think I'll do is shoot a photograph of someone in my pool to show the ritual purification aspect, and try to bring in other elements as well.
