As the two humbuckers will be pushed that bit closer together by having 24 angled frets, you'd probably want to pick pickups with different characteristics rather than having two of the same type, otherwise you'll notice a much smaller difference in sound when switching between the two positions.

You may want to space your control knobs and selector switch out a little bit more as they look a little bit tight to me.

Also, the volume knob is a fair way back, so isn't placed for quick volume adjustments with your hand. All depends if you find the volume knob position on a Strat useful, or you find it gets in the way and you keep knocking it. At the moment it's roughly equivalent to the neck volume knob position on a Les Paul.

Your bottom E string doesn't look like it will have the straightest string pull over the nut. Top E looks pretty straight, so having the strings bunch up a bit at the headstock will look a bit odd. I'd suggest checking the string paths and maybe moving the lower tuners to the right slightly, and widening the headstock appropriately.

The bridge looks a bit too offset with respect to the centreline. The difference in radius between say a 0.010" string and a 0.048" string is 0.019" or 0.5mm, in order to get the strings running parallel to the sides of the neck. Your offset looks to be nearer 1mm. You'll undoubtedly position it empirically, but you may as well get it right now, in case it does affect the overall guitar geometry slightly, as you are using the sides of the bridge for the neck layout.

Can you show the neck pocket outline and confirm the neck shape at the pocket end? To me, assuming it's a fairly standard bolt-on neck, the pocket doesn't appear to provide much support on the treble side, and you could probably only fit one screw on that side unless the neck itself was elongated beyond the end of the fingerboard. Or is that whole centre section up to the bridge part of the neck and it''s all bolted in, with the bridge fixed on the end of the neck?

If you made the hook part of the headstock out of steel, you could use it to take the caps off beer bottles.
