This is my favorite shape. Low profile, so a 12 fret cutaway lets you keep your thumb on the back of the neck up to where most 14 fret cutaways do. You'll for sure need a tenon to do it with bolts, and possibly an extra large one. The fancy curvy cutaway transition is only possible with integral neck, though. The heel is laminated from two pieces, with the seam running up the centerline (much nicer looking than stacked slices, IMO).

Here's another one of my favorites. Designed to look like a crescent moon from the side, fitting with the outer space theme of the guitar.

And here's a shot of what it looked like while carving. It was actually a "necessity is the mother of invention" because I didn't have enough walnut to make a full heel block, so I needed to widen it out with something
