That looks fantastic!
Very unique without being weird.
If I were to be overly critical I would say that the transition between the square centre area of the body could flow better with the neck. I do have a suspicion that there is a technical reason for that particular design, though.
The rectangle area under the strings is a hollow ramp that allows any pickup configuration. If you decide later on you want a P-bass or a Jazz or a MM sound you can make that happen without modifying the bass..
