I'd also make sure that there are no lengths of bare signal wire that could end up touching the side of a pot and grounding the signal. There are a few lengths I can see in the photos that have the possibility of doing that, so heat up the solder, push the wire through the hole in the tab on the pot until the insulation is touching the tab and then hold it there until the solder sets.

Also, I can't see a need for a join in the ground wire going to the jack. The green wire is more than long enough on its own, so I'd cut and remove the grey wire, especially as that uninsulated section of wire where they are joined also provides a risk of grounding out a signal connection when it's in the guitar. You've got no real control over the wires once you put them inside.

Have you marked out where the F-hole will be? You want to be able to run the cables around the F-hole so that they aren't visible, but as shown in the photos, you'll have a couple running directly across the F-hole. Taping wires together can help keep them in place.
