Not a bad start. My personal bug-a-boo is the toilet in a narrow, claustrophobic room. And large bathrooms (especially on a north wall) are often cold, will you have heated floors?
But 16 acres in upstate New York? Wow, you need much more outdoor sitting space than that current porch! It must be beautiful with all sorts of songbirds and wildlife. My previous house had an 8-foot deep wraparound porch on three sides. There was always a pleasant space to sit, in shade in summer or in the spring & fall sun. If wrap-around won't work for you, at least provide for a nice deep deck.
