That's pretty nice. Everything seems to be very organized.
On the house farm stuff: I would cut back to open space if you've already purchased all the plots of land and have a few million bucks saved up. You can build bigger parks, decorate buildings, etc. if you open up space. But of course keep houses, mix them up to build neighborhoods.
I would also move at least one skyscraper to your downtown area.
The panorama makes the estates more noticeable, but I wouldn't worry about it. They are totally inoffensive and actually look pretty decent. If you need cash, go ahead and earn it.
