It could be assumed that most of the farmland is strung out along the river valley - in other words it's a bit down from the map so you can't see it.

The only thing I'm wondering about is the placement of your manor houses. Your industrial area is right next to your rich manor district. I dunno what kind of industry they do but most can be described using one or more of the following words: Smelly, Noisy, or Smokey. If I could afford it I wouldn't wanna live next to a metalworker, tallow candle maker, or leatherworker. =P
