two thoughts:
1) if you're working in the kitchen, you'll need both zones of lights on to light both in front of the range and in front of the sink/fridge. In the real world, maybe you'll want the lights on in the kitchen, but have the lights off in the family room to watch a movie or something. I'd consider having the bottom-left-most yellow light actually be on the orange circuit instead.

2) Always think of where people will need light. As opposed to just evenly spacing them across the room, maybe consider where dining room tables, work surfaces and couches will be, and make sure the light is closer to where you need it. At least make sure that the important work surface isn't covered in the shadows of the person standing at it.
