Hi! Welcome to TFP. You'll get some great advice here about your build, whether you like it or not. Ask lots of questions, you'll get lots of answer. I tend to play devil's advocate to give you some alternate ideas to think about. Use any at your own risk!!
Jim knows of the "lite" versions of the ET controllers having helped me limp by with mine. It's awful. Heed the warning: NO LITE!! ScreenLogic is awesome, requires no contemplation, just get it.
One question... who mows that lawn all the way out to the mountain side?!?
You mentioned a concern about size. If I was building a pool, this is what I'd do, though it will sound silly. You "painted the pool" onto the grass, and that was a good first step, but I'd go further. Get some stakes and some good, strong string from HD. Stake out the pool and run string between the stakes. Just loop the string around the stakes so you can adjust. Then do the same for the deck. Include the spa, steps, baja deck, everything. Take your time. Then place your furniture out there. Chairs, table(s), lounges, etc. In the pool, too. If you don't have the furniture yet, simulate with what you have. Or use more stakes and string if you have to. Then walk around the pool and deck, around all the furniture, view it from all angles and from inside the house. Picture scenarios with different numbers of people. Pull chairs out from around the table. Lay towels on the ground for laying on (kids do that). Fill the "pool" with floaties (the kind you lay on). Buy them now, or simulate them. Nothing fills a pool and its deck up faster than people laying around on stuff. Lounge chairs can be over 6' long. One that you lay on in the water can really jam up available play room. If you plot out a table, but don't consider what walking around it with the chairs pulled out will be like, you'll be kicking yourself later. What about little end tables for drinks and snacks? They take up room, too. Umbrellas? Where is the BBQ smoke going to blow relative to sitting areas?
Case in point (based on how it's rendered). People and kids like to walk/run around a pool. You've got a traffic jam going on over at the fire pit. It completely impedes traffic flow around your pool, and that's with empty chairs. Just one guest with his feet up on the pit and you all will be stubbing toes on chair legs to get into, out of and around that circle of chairs. Now is the time to lay out everything, not just the pool. Once it's in concrete, your decisions will literally be in stone.
Kids and people splash. I'd want 6' minimum between pool water and landscaping. More if there's to be furniture.
I don't see that fire pit location as practical (though aesthetically its awesome). I see people, at night, congregating around the space between pool and house. That's where I'd want mine. Not a trek-around-the-pool away. Access to bathroom, kitchen, patio table, house, etc. That fire pit would get used more if it was on the other side of the pool. It would become a focal point of that area, rather than a distant oasis that will strand people out there. Just something to consider, your use of it might be totally different than how I'd use it. Mine is actually on rollers, so I can move it around. Its gas feed is a hose that lays on the ground and runs to a tank cover that looks like furniture and doubles as an end table for the chairs and love seat that surround the pit. I can move it all around as needed.
All your pool lights should go on the near wall, none across the pool and none on the ends. They'll only shine in your eyes and bother you. They should all shine away from your house and where you will most sit out there at night. Another reason to move that fire pit. You're not going to like sitting over there with the pool lights on. And you'll want to sit around the fire with the pool lights on!
More later, as it comes to me (unless you kick me out of your thread!)...
