I hadn't even noticed ring beams three years ago (start of planning) ... :p
Looks good, I looked at the project (for the first time) just now.
I like the mix of old and new architectural elements.
The roof (or rather the roofs) looks "quite normal" to me, but the windows use modern possibilities.
It is already built and well done ... still this note:
I appreciate and love the charm of old (older) building elements (e.g. beams), but I think that if something is newly built, it can also be clearly visible (I wouldn't have made the wood look "old").
A craftsman who built something 100 (or 500) years ago and whose work we like today would probably not have thought of making a repair look older than it is.
I always think the age should (must) be visible. What matters to me are the warmth and humor with which a building is designed. Durability and repairability are the most important guidelines for me. Then comes the appearance.
If something only looks "as if," I always find that doubtful.
I'm just saying this as a suggestion because I like the building, not to complain.
