Thanks, folks!
It's also very much like where I live. Based on the Crieff Road, 5 minutes walk from me here.
The main difference here is that the Lochty Industrial Estate should be in the triangular field(the one between the police car and the bus) and there's a stream that should run parallel to the right hand road that runs under a small bridge on the main road, in real life, that is. I'll try and find some pictures online of the area.
I bet if an actual central pivot irrigation system type scene was made in TG, it would be classed as fake looking, even real satellite shots of them look a bit contrived to me.

I think you might be right about the rapeseed field, Henry, I could have probably got better results by not using a population at all there and using some appropriate shaders instead.
I much prefer this one to my first awful attempt, though.
