Counting guitars in Your thread that one is actually number 4, because Number 2 is a pair of guitars, isnt it?
Just a few thoughts on a matter of taste level:
To me, the new headstock shape is more appealing than the headstock of Your first guitars.
I like the modern Lang type soundholes a lot more than the wide F-holes of the #2-Twins.
If the top needs to be dark, i would like something like the tobacco sunburst of Your #2 more than the finish of #3. And i know it is difficult to find a color finish for the top which looks similarly pretty as these beautiful walnut sides and back. Why did You not simply leave that beautiful piece of spruce naturally blonde?
The bridge somehow reminds me to a moustache. I do not like moustaches
I would suggest designing a new, smaller bridge for that guitar.
I can also image more harmonic looking cutaway designs than Benedetto's which You seem to have adopted here. And - despite of the resulting smaller volume of the body, i would prefer a more slim, less rounded lower part of the body - again to my eyes a manko of Benedetto's shape which You seem to have followed more or less. Maybe compensate that by increasing the thickness of the body accordingly.
I also do not like if pickguards stick outside the body into the cutaway. From a mere technical point of view the width of just two frets is sufficient to mount the pickguard safely to the fingerboard.
But aside from these points this guitar is a real beauty, just like Your #1 and #2s.
Most of my comments fall in the category "matter of taste" but maybe also "feedback of a potential customer" which my point of view as an amateur builder still is (btw, my first and only fully self made guitar is an archtop, too).
So in conclusion - really great work!
best
