It's rather pleasing to see a rural setting like this, but one that is organized and refined to reflect the industrial-scale agriculture that takes place on it. There's a beauty to it that is a distinct blend between nature and city.
...Hm. It seems like most everyone has already said good stuff. I really love the detail you've put into this. The shadows, the irrigation canals (and I think the river they spawned from), the small groves of trees... Good job, man!
Absolutely stunning piece. The detail of the farmland and the irrigation is one thing (and I do so love those rocks jutting out amongst them) and it's insanely details and wonderfully done with the shadows of the clouds and what not, then the mountains that reach for the heavens add so much more. I would love with all my heart to walk in those fields and take in that wonder.
