OK, this is originally a 3D model that I'm turning into a matte painting.
It's supposed to be sort of a wasteland or junkyard of large scraps (you can get a sense of scale from the figures climbing on the spindly thing).
My problem with it is the water... it seems a little too "ripply". I had originally wanted the liquid (it's not water) to not look like a sea but instead like some kind of liquid that has less surface tension; something reflective despite the pollution.
Because there appears to be current lines on the water (I hadn't intended for this to happen), I was wondering if I could convincingly portray these things as drifting.
On top of this, if I were to "fix" the water, I want to do it through painting over the piece I already have, not re-rendering the 3D scene.
