It looks really nice, but the forests still look clean, and lacking in dead branches, pine neeedles, fallen pinecones. General shurbs, bushes and foliage would do wounders for the graphical appeal. What I was thinking was texture to do this, because it would look extremely nice up close and as secondary function would look like a shadow afar. I still think that implementing it would be a good idea as it would look really good with the shadows that are in already.
