Tyre clearance looks a bit marginal, the filing around the brake hose ports could be better, and I've no idea what's happened with the brazing between the chainstay.
The biggest oddity for me is the brake bridges for a bike that doesn't have mount for mudguard.
Why? There's a perfectly good structural reason for having chainstay and seatstay bridges apart from needing to have something to hang a mudguard off, even with disk brakes.
