Mountain River Scene/ Cave Scene Now[C+C PLZ]

[Johasu]

Worked on the water some.  Not sure about this yet.  Looking at references of mountain rivers and streams.
Played with the trees some and brought the background trees to a lighter color as suggested.  (Edit:  I'm still playing with that gravel.)

I personally think Tapsu nailed the water in his edit above. Maybe it was a bit too dark, but certainly I would go in that direction. If you want some bright water, then that would suggest a lot of movement, ripples and waves. Having it so bright and yet so flat doesn't make sense, it makes it look like the water is filled with bubbles (i.e. carbonated). Again, I would try something closer to what Tapsu suggested.

A few reference links I have been glancing at.

Not to argue, but most of the references I am using (general mountain river/stream scenes) show much brighter water.  The sunlight reflects from the open sky above and even in darker thinner expanses the water is still the brightest area of the photo.
Very shallow streams have a dark appearance like this when you can see the rocks directly below the water.  Evening scenes or heavily shaded areas tend towards darker waters as well.
I have attempted a few stabs at a much darker water like his and haven't been satisfied with the results as of yet.
Maybe I'm going too dark.  I don't know.  At any rate I haven't been able to nail down a good feel with darker colors the way his did.  (    )

Worked on the water a bunch more.  Taking the reflection of the light to a new level and working with the shallows reading darker.
Cleaned up some stray pixels and such in the trees and that too.
Comments?

I did this cave before the mountain river.  I was going for a dirt floor and cool stone walls.  I came up with this brown/blue color scheme.  I'm particularly frustrated with the closest wall segment , but happy to take comments and criticism on any and all factors of the piece.

Is the color setup ok as it is or is the floor too far from the blue to feel acceptable to the imagination?
The way I did those crevices within and contours on the nearest wall feel way too contrasted to me.  Advice on how to fix it?  Is it simply a matter of adding a few more colors to lesson that sharp edginess between the colors?

Thanks ahead to anyone taking the time to throw advice or input.
Still taking advice on the river too if anyone sees anything that I can improve upon drastically.
