Hmm. Seems very noisy to me in the lower part. Personally, I would have set up on a tripod, put my ISO at 100, raised the aperture, and then put the shutter where I needed it to be to make the right exposure (except if the wind was blowing).
Anyhow, I think you should try a lower ISO with a tripod.
Compositionally, the grass is nice – except for where it is flattened. I would have liked to see a field of tall grass. But maybe there wasn’t enough where you were.
All things considered, it is a nice shot. I personally know the challenges of working with ISO while hand-holding at sunset.
