Great look - love the matching. You have one of my favorite engine bays on the forum!
I like your grounding kit, but I think a few of the grounding points you have picked could be better. A couple of them are not giving as much benefit as they could be. To improve the electrical system, you want the shortest path to ground as possible tying factory grounding points to the kit wires.
Just under your harness cover there is a factory grounding point, then your kit about an inch away. Tying them to the same point will lower the resistance reading on a meter. I found that you can move two of the factory grounding points to a post UNDER the Rare JDM Harness cover, then link them to the grounding kit. Check out this post for reference:

If you are happy the way it is, cool. Your set-up won't hurt anything.
