Nice colours. A very warm image. I live in the English Lake District and it's raining so hard at the moment I can't even see the trees! Nice scene, but you might want to improve the smoke and put a bit of an "old" texture on the tractor paint. Also, making the path more distinctive (a bit of a muddy terrain) and altering the tractor's direction of travel would be a good thing (it looks like the farmer's about to crash into the fence!) Bring him & his tractor nearer the camera, too, then you'll have a superb scene IMHO!
