I agree with the ones who said it lacks detail and sharpness, and I could have cut a bit more of the grass, although I personally like the square format.
Last but not least, I would like to thank the sheep for standing so still! :)
The more I look at this picture, the more I like it. You have managed to create a piece of art, in addition to meeting the challange. I would hang this one in my house - good job!
Not wild about the square format for this. Rather see it trimmed on the sides and just a little off the top. Otherwise, the colors are great, and I like the sheep standing on the horizon line. Very fine.
imagine if you had about 7 or 8 of them all lined up on that rise? very cool concept! :) I would have cropped this a bit tighter to get a better view on the sheep.
The compostion is good with all that grass at the bottom. It seems your sheep are not the main focal point though and that your focus is more on the grass in the foreground.
nice image. nice how you caught them lined up like that.
suggestions.... : framing the shot to incorporate more grass or more sky... for a negative space effect would be very cool, and add to the drama of this shot. The horizon is almost at mid photo.. not quite, but almost. It might be nice to deliberatley emphasize one or the other.
