Beautiful job on the wiring, it is looking very good.
But add a few tie wraps. One goes within a few inches of the start or ending of a bundle of wires, and then every 6 inches or so inches along the length of the bundle and also at any break outs from the bundle that go off to the different fixtures.
Sorry can't help it, I used to work at Boeing creating wire bundles and also worked inside the planes with them and had to know how these things are done. The tie wraps help reduce the strain on the individual wires and prevent accidental snagging of loose wires. Rubber nails are used to fill in any slack inside of P clamps so that the wires can't be pulled around in them. A piece of rubber screen spline can be used or some such soft object that fills up the space so there is no movement within the P clamp.
