A little too much foreground and background and not enough cows. :) I'm sure you were trying to make the picture interesting by including the flowers in the foreground, but I'm not sure it works in this case, given the challenge theme.
Pretty shot, love the spectrum of textures and colors... the shot appears to lean too much to the right, though, the mountains on the horizon are close, but the rows of corn definitely make the shot "lean". - 6
There are a few simple things you could do to drastically improve the quality of this shot. Tilt it slightly left so that the horizon is more even, move up a little bit (or possible even left, but I'm not sure cause I'm not there) to get rid of the flowers that are so close in the immediate foreground, and use a larger f# to increase your depth of field.
THis is a very nice shot and you used the rule of thirds well. the flowers in the foreground really detracted me from the main subject the cows. The flowers are beautiful and vibrantly colored it is only after stare a while do you fully comprehend this shot.
