Thanks for the comments, I'm still working on the graphics.
The trees are rendered in my special tree system, so they are meshes up close and sprites at a distance...there are shadows up close as well; I will add more distant shadows later which will hopefully fix this problem of the lighting not matching.
Terrain texture is pretty high res, maybe it just looks blurry in these screenshots.
Rocks aren't really done yet, they sort of are just for filler right now.
The shots look good, and from seeing them it can be said this project will entirely look very good; The concept sounds a bit like Stalker or Fallout 3, what also is good. So, looking forward to see more.
