I like the overall feel of the colours...; however, at the front bottom (left of the closest roll) the grass is anti-freeze green . Might want to lower the saturation selectively in that area (do a general selection by drawing around it and then select the green colour range), from here play around with the colour sliders and lower the saturation to make it more shadowlike and less "glowy". The trees are perfect. They evoke a "fantasy" like feel with their slightly unreal hue (that's a good thing ). I would darken the sky a little bit to bring out cloud detail (not nescessary but would enhance it). Other than that great shot and great composition.
