I had a very nice sean set up There's a nice Sean? Okay, seriously, the problem seems to be that you have no bottom lighting. You want the water plane to act like a RW one that reflects and throws off ambient light, and Poser stuff, whether 4 or 5, doesnt do that. So cheat. Put a couple of dim spotlights under the figures: place them on the camera side, facing up at about a 45 degree angle. You'll have to play with them a bit to find the right intensity, but that will give you the suggestion of bounce light you're looking for.
