First off, I think the slight oversat works really well....I guess you just had to be there to realize that the back cow seemed to be the mother...Good shot nonetheless and I hope you end up doing well...
were is the before and after, i now that the name says future hamburgers but the best pictures are the ones were you do not have to look at the name, would have been better is there was a hamburger in the picture
My first impression was, "Gah! That's way over saturated in the greens." It kinda grows on me. The grass has an eerie glow. The orange fringing around the cows' ears is a nice contrast to the green. The blueish sheen on their backs is reminiscent of a comic book rendering of black hair (e.g. Superman). I think you needed a burger in the shot to meet the challenge.
I think this shot shows the before and the title explains the after, but would have liked to see both in the actually photo. Photo itself has nice greens, and way to get all the cows looking at you. Their faces are a bit dark (because the light is coming from behind). Not bad. =o)
