I think those trees are scary....
You've done some good work here though, like you have the basics down. The field texture should be separated from the road in my opinion, by either a ditch or some open space or grass or dirt and/or a fence line with a dirt road inside. The farmers won't plant out to the road shoulder, and they won't pull their implements out onto the road to turn around and go back up the next row either. Oh, I'm sure it happens somewhere, but it's not the norm.
You're doing well though, keep it up!
