zescanner, The updated image is coming... its just taking longer to render and tweak then I expected, even though I'm using plop-renders. :) [I suppose it doesn't help that I'm working on multple projects at once.] Erlik & bigbadelf, OK, yes, we misunderstood each other about the "oil stain". Erlik, are you refering to the darkening of the pavement around the green water as well as the green water itself? I do agree that this looks odd. It was my poor attempt at trying to make the pavement/concrete look wet along the edge of the water. Even though the croncrete is painted yellow, I was trying to simulate the effect of the water soaking into the concrete. I think the really big problem is that I made the water much to thick. For speed I modeled the water in Rhino, but since I've never tried to illustrate water in this way I'm still learning and figuring out how best to do it. Next time I'll have to use meta-balls for the water. In the meantime I'll try sinking the water object further into the concrete and pavement. Back to work...
