It looks excellent and was fun to play on. I can definitely see that you've put effort into all the details and added lots of animals. Great work!
I noticed some slight bumpiness in the road. If it is something you want to fix,
this tutorial may help, but I can understand if you want to keep it bumpy.
I also think it could have a more descriptive name, as there are already some farm add-on tracks. Autumn Farm? Calm Farm? The Farm Trail?
Finally, there's an opinion in the Blender track settings to allow driving the track in reverse. That would be good to have on this track, since it looks great in both directions!
(I notice that your track is listed as a Featured Track, nice!
)
