Dan, these are scenes I also enjoy photographing - the attraction of fast flowing water....
Did you shoot hand held? The IS seems to have managed quite well. I would be inclined to burn in the bright rock on the river bank as it draws the eye somewhat.
Also clone out the small dark area along the top edge.
Len,
Thanks. I actually used a tripod for this, although at 1/15 second, the IS should have been fine.
I appreciate the suggestions. I think removing the dark spots is a good idea. I might also include a tad more water at the bottom. Seems a little tight to me.
Re the white rocks: I obviously couldn't get across to check, but that's probably marble. There is a lot of relatively low-grade marble in the area, mined for industrial purposes rather than building interiors or the like. I burned that somewhat, but I'm not sure I want to burn it more. It's actually a pain--a lot of it is light enough that burning ends up creating a gray tone, so I have sometimes used a multiply blend instead.

Nice image, the shutter time of 1/15s has just left enough movement to be interesting.
As for the white rock, it does draw the eye a bit, but it's not badly positioned in the frame and I dont mind it at all.
Thanks. I had actually been playing with shutter speeds, as the OM-1 has a computational ND filter that let me emulate slowing the shutter more. (It does it by compositing multiple shots and saving the composite in raw format.) I tried a variety of speeds for a shot in a different direction. What I was aiming for was to get smooth areas to convey motion but without obliterating all of the structure.
