Beautiful! Well admiring of your skills, application and aesthetic.

Love the headstock. Is the build Benedetto inspired by chance?
Yes, the Benedetto book was my guide for this one and I stayed fairly close to it. But I did need to use other resources as well; Benedetto doesn't exactly give away all of his secrets!

What does it sound like? Did the mac bend very easily for the sides? What are the other timbers used? I'd be keen to learn how you carved/tuned the top. Is it X-braced or "parallel" bracing bars. What's the size of the lower bout? To be honest, I'm surprised that mac works for the neck. I didn't realise it has good beam strength/stability.
It actually sounds pretty decent. It is warm with quite a bit of low end and the mid-range honk characteristic of a carved archtop. It's lacking in top end, but that is probably more to do with the craftsman than the materials; I've been able to get much more top-end bite in more recent builds, and I'm confident I could bring it out in macro as well if need be. Not my ideal tonewood by any stretch, but fun and easy to work for a first attempt.
This one is 17" and x-braced (another reason for the above tonal characteristics). I've done parallel braced as well and if I were to use macro for a top again (which I probably won't!), I'd go parallel for a brighter, punchier sound. I wouldn't make a habit of using mac for a neck, but this one has stayed strong and straight. It was a nice, dry and perfectly quartersawn piece.

I have a couple of old Hofners (one's a carved Committee with rosewood back and sides, the other's a steam/pressed top) and a 1937 Gibson L-12 so I'm pretty keen on arch-tops

Wow, a '37 L-12... nice! I also have a nice '56 Hofner 459 with a carved spruce top, as well as a newer Jazzica Custom. Nice to see more archtop love around here!
