I tend to agree with rexbobcat - you are trying to get too much in one image. I would have isolated the stream on the right and made it the subject of my composion. I also think that you have over-exposed the stream on the right a bit, as it is just a bit too white, even blown out a bit in the lower half, whereas the rocks seem to be a bit under-exposed. Let us know the details of your exposure and if you used an ND filter and maybe you can get some pointers for next time. HTH.
