Sprinkler design question for diverse 2000 sq ft lawn with slopes

Hi, I am working sprinkler design for my home lawn consisting of MP Rotators only, mainly because of sloped terrain and windy conditions. Since it´s my first design I would like to ask for a quick review if I made some serious mistakes with sprinkler heads positioning and dividing them in zones. I studied for quite some time all the design guides from the Hunter but since my lawn is much uniform it was quite difficult for me to keep it head to head coverage.

First I used Orbit sprinkler system designer - an online tool - to draw the plot precisely and had it automatically populated with sprinkler heads. That resulted in very uneven irrigation patterns so I started the job manually with creating arcs and counting GPM for each zone.

My water source is a water well and now with 1" piping going form the pump I am able to get 2 gallons of water in 8 seconds. Static pressure is constant at about 3,8bars (55psi) when valve is either closed or open.

Here is link for the design:

Appreciate any help.
