I think this one is starting to look pretty good. Since last version
I've changed the texture on the trees, fixed the problem I had with
media and turned water-plane into an isosurface.

Took 25h 30min to render with pov3.7-b29 on AMD64 3500+.

So, any comments, critiques, anything?

Very nice water (texture, reflection, basic shape)!
One thing I'd suggest is making the water interact with the shore a 
little more, right now it just seems to flatten out at the edges. With 
real water, the height of the wave above the neutral surface plane 
changes with the depth, with waves slowing down and getting both taller 
and thinner as they reach the shore. Right at the shore they may break 
if the seabed has a shallow angle, though maybe not with waves this small.

Similarly the waves seem to remain the same height as they go to the 
horizion - usually at that distance various frictional losses and such 
in the water will make the ripples decay, which doesn't seem to happen.

Think about what is causing the waves, where is it and is it really 
making such uniform disturbances?

Great image! I actually had to go back to the original
thread to convince myself this was the same scene just
with some considerable improvements ;)

The water horizon looks a bit oddly shaped to me. It may
be the wave function, your sky object, or my eye-sight ;)

I'm not sure if the sailboat is deliberately just a "placeholder" for
your final design, but if it isn't, then I think it's a bit too plain
and lacking in detail. Looking at real sailboats might give some ideas:

  Flags, ropes, details (and better shading) of the sails...

The sails still need a bit of work. It's textile, so maybe a bit of
transmittance might work. Anyway it needs some more texturing.

That said - impressive shot; a well invested day of rendering time!

I liked your original, and now it's looking even better!

I was wondering about the main water waves: Since I can't really see what they
look like on the 'other side' of the boat, I'd suggest ending the current water
object AT the boat (as seen from the camera), then making a 'mirror image' of
the wave object for the far side of the water. That way, the boat will appear
to be cutting through the water, leaving angled wakes on BOTH sides of its bow.

The other thing I might critique is that the water waves seem to be at too much
of a right angle to the boat's direction.  Perhaps that's just the camera
angle; but I think they should fanning out from the boat at maybe 45-degrees or
less--in other words, the wave direction being a bit closer to parallel with the
boat's hull (although NOT parallel, of course.)

I've looked at this image several times now and I think I agree with the 
others that the curve in the waves is unusual/distracting.  If they 
represent waves on the sea then they shouldn't curve like that.  They 
should probably remain parallel or curve the other way (based on 
interference as they enter the bay).  If this is a wake from the ship 
then the waves should fan out at a 45 degree angle as Kenneth suggests. 
  I think the problem I'm having is coming up with a reasonable 
explanation for the curvature of the wave pattern.  It's almost like a 
speed-boat just passed through the scene from right to left...  an 
explanation which seems out of place given the other elements you present...

Love the scene.  Looking forward to future iterations.

Really improving indeed. Very nice view.

The waves, like others already said, need more thought. Are they coming from 
the sea (at right)? Then they should curve the other way round due to the 
interference with the shallowing sea bottom which slows them down. They are 
obviously not the wake of the ship as they are also present in front of it. 
A slight wake (45 degrees) should be nice to add in that respect.

The scene is peacefully, beautiful.
Regarding the waves, we don't see what if you have imagined at the left 
(a shore? the mouth of a river?), they are a bit unusual but I like them.
Tee boat (as Warp notes) compared with the overall scene (trees, water, 
...) needs perhaps some details.

The 45 degree angle is the angle for a precise speed, twice the speed of the 
waves in the water for a given depth. The wake angle depend on the speed of the 
ship trough the water and the depth.
Here, it's like there is something like a water fall somewhere to the left. In 
that case, there should be some foam on the water.
