Having the sky visible in a 3/4 view like this looks strange. The horizon should be way, way off the canvas, so this looks like the earth just ends.
I think the plain solid-colour grass was fine. The scale here is too small for grass texture to be visible. If you want to add some variation to the grass, vary the hue in different areas instead of adding texture.
The fields are very high-contrast and distracting. I think it would be better to fill them up with more crops, so that the dark ground is not visible. The ground creates a lot of contrast, and makes the fields look sparse.
