Looks OK, a couple of tips
1) I always heat shrink crimped or soldered connections, I believe it add a level of robustness to the joint.
I use the Marine heat shrink tubing, there is a sealing glue that bubbles out, for a water proof seal.
2) For my home wiring jobs I always do a pencil drawing identifying the circuit path, can be pretty crude and I file it away in a binder in the garage, saves much time a year from now if you are changing the circuit figuring out what is wired to what.
3) I also use wire number tape and give each wire a number code and that is used with the pencil drawing mentioned above again, big time saver when trouble shooting or revising the circuit. I number the wire at the buss bar or fuse then apply the same number to the wire at the component end of the wire,, alternator, electric fuel pump, light ,,,
here is an example of the number tape, can be found much cheaper at other internet sites
