Hey Don, I hope ya' don't mine, I pull'd what i think was the images you were trying to put a realistic waterfall in...

I did this in Photoshop with alot of bluring, smudging and slowly building up white and blue tones. Water does not fall straight down but bounces off outcroping of rocks. I added another source of water off the side because your rock structure allowed for it (hope thats ok).

If i had more time i would blend better but wanted to show you "you can do it in postwork" with PS.

Enjoy,
