This piece is done with a complimentary color scheme. The fist has a pitiful amount of wheat in it. Unfortunately, the distant details aren't fading as they should. The distant wheat should be less distinct than the wheat in the foreground.
Here is an excerpt from a half-sheet piece I did today as well as a black and white, preliminary value pattern sketch. The painting as a whole didn't turn out so well, so its dead weight was trimmed.
