They may be tame and we all can't go to far away locations and people often overlook opportunities because some things seem commonplace or ordinary. Don't let that hold you back; not all of us live near farms or fields and have the everyday opportunity to capture their sense of openness, vastness and isolation. Sometimes the skill of a photographer emerges when he or she can take something ordinary and make it stand out as you have done. Sometimes fantastic shots have been taken in people's backyards or in their neighbourhood.
In the first photograph there is subtle drama as one can sense the energy in the dark (and scary-looking) sky and cloudscape. One can imagine that the shot was a harbinger of a nasty storm. At any rate, the clouds in the upper right hand quandrant look almost as if they were from a painting; not something that one can capture every day. There seem to be small rolling hills or mounds in the distance. The different hues of green in the grass are interesting as are the grey-blues of the sky.
I like the clouds; such an unusual formation.
The four tanks/containers/silos (?) are interesting and contrast with the crop in the field, which is what makes the picture interesting. Just curious but what is the crop and what is in the containers? The photo shows a great vastness and it might be worth considering experimenting by cropping either a portion of the bottom or top of the picture. Also, you may wish to experiment with having the tanks in the field just slightly off centre in the photos (again, cropping may help with this).
All your photos are interesting and give us a different perspective, so thank you for sharing.
These feel a little tame compared to other contributions. But ya shoot what ya got.
Feedback welcome.
