That is really nice. I would make one minor comment - it's something I've fallen foul of myself when changing pickups on one bass. A chisel is fine up to a point when cutting out pickup cavities (and, in this case, bridge cavities) but looking back at my own work, I'd say that ideally I should have a 3 or 4mm drill at each corner before doing the chiselling, so as to have rounded corners to the cavity. It isn't anything that anyone will ever see so I'm not that bothered. Your skills are far, far greater than mine anyway, and that is a lovely bass - I especially admire your blending of the three parts of the fretboard together, that is absolutely stunning.
