TBH i like the grass the way it is. I think the top two pics in your OP look better than the sterilized pics of grass in bottom two. Not sure how many wild fields and lush forests you see but there are many different types of flora and fauna and not just your standard Bahiagrass. What I think will make more of a difference with the athetics of the screenshots (you are comparing alpha pictures to a finished product) will be the inclusion of better lighting and the finalization of the animations (like the transitional animations) you know, the things they have already said they are going to implement.
