Is this meant to be for a video? Interactive? Just stills? The first picture you have is a good angle for the scene. The layout looks natural and not manufactured. Currently it’s hard to tell what in the scene is the way it is because of your video card, or because of low quality/low resolution assets. I agree with the post above that you need to soften the shadows (with daylight), and the scene needs foliage. All texture and shadow resolutions look very low at the moment too. I would also use a very pale orange as your light color to give more of a warm sunny feel to it. It’s a very good starting point so far.
