Looks pretty good in the pics mate. There is a lot to take on with your first build. If you go back and read mine (from only a year and a half ago) I'm paranoid about all sorts of things...
A couple of people have already mentioned this, but you really need to do a dummy install of the bridge and work out where the neck needs to go for correct scale length. It is not as simple as butting the end bit up against the cavity.
So put some tape around the bridge post screws so you can roughly centre them in the holes, and pop the bridge on. You want a measurement of 628mm from the inside edge of the nut to the bridge. I tend to go for the high E saddle being around 3/4 - 4/5's of the way forward (towards the pickups) and getting that at 628mm. All the other strings will need to be slightly longer to intonate properly. So long as you have adjustment backwards you are all good. You will probably find the neck needs to be pulled outwards from the body a bit to get this measurement right.
This is also a good time to temporarily install the high and low E tuners and run some ordinary string from them to the bridge. This will let you see if there is a big enough break angle on the neck and that it is nice and straight in relation to the bridge- ie both strings run evenly down either side of the fret board.
Here is a pic of me doing that on my recent semi scratch build:
