I personally would think about moving the outhouse away fro the crops and more towards the corals. If/when it get full or floods the raw sewage might flow into the roots of the crops.
What you could do is move your house up where the Chicken Coop is now, relocate the coop down a little bit and to the left of the house and place the outhouse between the repositioned coop and the left corner of the coral.
But overall, every thoughtful and clean layout.
