The ones I liked with the 2nd and last picture. The last picture could use some higher shrubs around the hunter... Because hes like a big black dot on white paper.
These are pretty good. I think I'm getting sick of all the terrains with really good lighting, kinda miss simple stuff like this. Or I'm just jealous that everyone else surpassed me.
They could use some more details and environmental doodads (especially the third one). Some of them could use a bit more height variation, and the camera in the first one it way to close to the water in my opinion. It looks really strange having the camera that close to the water. For most of them the fog is fine, although in the third one it looks like you have just got the normal black fog, which you should change.
