Looking very nice, great layout. I'm just a little distracted that your pond has no inlet or outlet. The addition of one, the other, or both would , IMO, be an improvement.

Add a smaller course roughly perpendicular to the present river, run through the pond, add a bridge or two over it (as needed), cut some fields minimally, add irrigation ditches from new course. (My .02, sorry to be a pain in the a**)
