I would try to use more muted light inside the water and like Geekster said make that light dance on all the walls. Whats with the line voltage or low voltage recessed ? Will you be retaining these ? Make the water dance and then place some 20w (or maybe 35w) mr lamps below the tuscany signs. I like the idea of the pars to fill things out. We did a 2 ft deep fountain with 10w lamps grazing a wall and 20w on the statue and it came out teriffice. Obviously you will need more punch on this here. Ecellent project and I look forward to seeing your demo and finished project.
