I've done a xcf so you can play with the water I had saved the other in png how naughty of me. If you want me to the bridge and the trees let me know

Lorri, this is by no means a work of art that I did, but I think if the water fall looked like it was coming out of the sky, instead of starting at the bridge, it would look better. I just played around with the smudge tool and the blur tool. The smudge tool to push some of the water up into oblivian and the blur tool to soften the edge of the waterfall.
I am sure you will be able to do a much better job than me, mine was sort of rushed.

Molly I think you will find one is ok

very nice

I know i could do it if i keep playing with it
