I agree about the appearance of the pickups, with the big "Bartolini" across them; however, if they give you the sound fidelity you were after, then it's more than a justifieable trade-off.
Thanks for the bit on making your ebony pickup mounting rings (I believe you called them covers, which confused me for a second, though it could have looked interesting!). I was planning on making some of my own, and it hadn't occurred to me to do it as a walled 'box'-- I just have a semi-thick hunk of ebony I was going to shape.
As for the rest-- there are 2 other things that I didn't absolutely love--
First, the elongated headstock. It suits the guitar better than a 'Gibson'-style one would have; however, I still see it as being a bit long. What I DO like, though, is that it has its own look, which is more than I can say for my own or many others around!
Second, the flamed headstock veneer and tailpiece. I like how solid black draws attention to the subtle beauty of spruce. I found the flamed wood looked a bit 'much', and didn't marry the spruce as well as something understated might have.
For proportion, other than the headstock, I like it. I think you've created something unique, and something that's balanced, to boot. Sure, it's smaller than standard archtop design, but it was never meant to be a traditional archtop replacement, and I think its own aesthetic and your vision are successful. Despite my criticisms, I would cheerfully brag about this guitar to anybody who I happened to bump into... at a gig... at a music festival... at my local grocery store... !
