Beautiful! The welding looks amazing. I find the overall appearance to be quite pleasing.
Interesting change in the seat tube/post from round to ovalized and the addition of the horizontal top with the adjustable QR on the mount for moving the saddle forward or aft. The only down side to this is there doesn't appear to be any means to tilt the saddle nose up or down to change the angle to suit the preference of the rider. Possibly I am wrong about this? It does look relatively easy to swap the saddle for a rider's preference, say a Brooks Professional or Swift.
