Excellent, Nay, AMAZING first project! Just a couple tweaks and you've got a mutli-grand custom shop killer bass.
First, I agree the pickguard needs trimmed. It need to be trimmed such that it leaves just an even thin line of visible wood along the edge (especially at the horn where it seem to sort of hang over the edge). And then of course beveled. But my opinion is that in spite of the Ibanez neck (which is an idea too cool for words, I mean people are always putting a Jazz neck on a P-bass, so why not go all the way to thin and fast? That's a custom bass worth some cash!) I don't like the clear pickguard. Too high techy for an old-school bass. My suggestion

use the trimmed clear one as a model and make a tort guard (beveled natch). Yep and be sure in making the new guard that you've moved the pickups over (means the hole in the guard needs moved too!) As mentioned by others, strings are supposed to lie between the pairs of poles for that kind of pickup.
OK. We are getting there. There is only one thing left for that killer piece of wood you made this bass from. Namely about 10 or 12 coats of tru-oil finish. (It's for hand-rubbed gun stock refinishing, find it on line. Many coats of Minwax poly or Tung oil rub will work too ) Yep, Building a bass or guitar is always about the finish on the wood an you got the materials here for a truly GREAT looking bass, all you need now is the elbow grease!
And of course since this is TB, no evaluation would be complete without noting that in addition to a tort guard, flat wound strings are also
de rigueur!
(Just kidding about flats and tort. You get to use anything you like!)
In spite of critique, still A+ on project!
