I just got done inspecting the frame and I have few criticisms.
1. I agree with Lycc825's criticism about the cable stops being to close to the cantilever hangers. Rub might occur. Some kind of plastic sheathing around the brake cable in that area will alleviate the problem.
2. The left cantilever hanger is approximately 2 - 3 degrees off center.
Other than that everything looks fine. The paint job is gorgeous. The welding is satisfactory; I didn't see any butts that concerned me. No dents or scratches. All of the cable stops were centered on the tubes and parallel with the tubes.
I'm not a frame builder, but I find the build satisfactory.
