Are you using CPU or GPU rendering? Looks like you don't have bump showing up on your water material.

Did you add a 2-sided material node for the leaves in the file?

I did look at your scene earlier, after I posted. There are some very complex node setups in there that I can't make heads or tails of. It definitely doesn't work in GPU render, and I found that with CPU render you still have a lot of locally mapped textures, so not very much came through. The tree leaves node network alone was mostly incomprehensible to me. I wasn't able to do much with the file unfortunately. I dropped in some other materials from my library that worked fine in the scene, but I couldn't get any of the shader setups that were already in the scene adjusted in any way. (For example, I tried and couldn't add a bump map to the pool water in the scene.) Only thing I can suggest is to start simpler.
