So, I'm doing this for art class.  It isn't finished yet, and I don't 
have too much time to get it finished.  But, it is a start.  One thing 
that stands out to me is the clouds... the sphere is way too small for 
me, so I'll replace that with a plane instead... only problem is the 
27hour render times.

Comments and Critique welcomed and requested...

Thanks,
Allen

For different reasons, the clouds seem to press down on the landscape, not 
necessarily because the sphere is too small. The first reason is that a 
proper atmosphere is missing, either a fog or a media, in order to give some 
depth to horizon distance and sky heights. A second, more psychological 
reason, is the elongated format and high horizon, which increase the weight 
of the clouds. However, imo, the first reason is the most important. 
Otherwise, good work! I like this scene.

Ufda!  27hrs!  I don't have that kind of patience.  That must be why I never
bother with trying to do media clouds anymore.  Nevertheless, the image looks
good!  Patience pays off!

One thing I might suggest trying:  to add more interest to your grass, try using
a pigment function to vary the length and color of the grass.  For example:

#declare TheFunction =
function {
  pigment {
    bumps
    poly_wave 4
    color_map {
      [0 rgb 0 ]
      [1 rgb 1 ]
    }
  }
}


And then, when you are planting your grass (through whatever method you prefer):

(if POS is the current grass position)

  object {GRASS scale (1+TheFunction(POS.x,POS.y,POS.z).red) translate POS}


Depending on how you've done your Grass object, you can use a similar method to
vary the color of your grass.

Just something you might try.

Another, alternative, method you might like to try, is using RRand(A,B,seed) 
for putting some randomness in scale, position and color.
