The only suggestion I have is to use a lattice object for the water flowing out of the pipes, to give the water a more realistic look. the inset in the picture I've provided here shows how I drew the lattice object in the Terrain Editor. The object has the preset material for water found in the glasses category, with a bump map added to roughen it up a little. Great pic, by the way, and I like the camera angle.

This is not my "second childhood". I'm not finished with the first one yet.
