It is looking good though. I suppose it is mainly the grass that weights 
down the memory? I think that in your image it also accounts for a 
difficulty in judging the distances: the landscape seems smaller than it 
should be, almost like a miniature. I often do two things in landscapes: 
(1) I only plant 'grass' in the front half of the scene and use an 
adequate texture for the background; alternatively, using Rune's grass 
macro which is very fast and memory sober. (2) For simulating greater 
distances, I scale the grass (and trees) gradually down with distance 
from the camera. This optical illusion results in the perception of a 
larger/wider landscape. Inversely, in some cases, it might be 
interesting to scale up with distance, but that is another matter.
