why do you link to a banner on deviantart? :/

Whoops, thanks for pointing that out. I am not sure how I did that.

Here is the real link http://www.deviantart.com/view/8355644/

Nice grass; I think you can do it with procedurals (crumple, coriolis, turbulence), with a gradient in Bump (input parameter) with green dark at the end of the ramp, and you can maybe make looks better than that using some velvet plug-in:

or the Leigh´s trick:

or both :)

The illumination however, I don't find it so good; in fact isn´t entirely an outdoors illumination, unless we speak of a very cloudy day, thing doesn't notice in that sky.

For this type of illumination, you should keep in mind 2 components:
1. The light of the sun: that spreads in straight line and radial sense (but as being to 48 000 million kilometers of distance, we only notice their lineal aspect and their parallel illumination) for what is recommendable some type of light that cast parallel shadows (distant light). Commonly the sun shadows is represented by blued color, although the light of this is yellow.
2. The terrestrial atmosphere: produces a very interesting illumination effect; is as a diffusion filter of the solar light (as if this was another light source). This light source is diffuse (what means spreads in radial sense and cast soft shadows, commonly represented with neutral or warm colors).

To achieve this type of illumination, exist many techniques you can use. Here some:

For the ambient lighting, if you have time, backdrop radiosity will be enough, you can also use area lights for atmospheric shadows and if you want, you can add a distant light (yellow tones) with blued shadows, for the sun light.
Another way can be with the archi-famous spinning lights, the Overcaster of Ekki Halkka is a good beginning:

You can begin with a Gradient Backdrop, then add an Ambimage (some point lights also helps); for the environmental shadows (softshadows) add OC_Shadows (neutrals colors), for the sun you can add a distant light (blued shadows) or an OC_Sun with yellow tones.

Recently, I made this with spinning lights for a TV banner of a detergent (yes, another TV banner :rolleyes: ), isn´t something realistic (the idea was it looked like a scale model) but the principle is also applied:
