I just did a harness on a guitar at my shop that had those on it, so I got to have a nice look at (and under) them. They look good! I think the gold color used is not bronze and the green is something like spray paint. That's fine, of course. They just won't continue to "evolve" and show more green over time as the oxidization occurs, like the originals. Please understand, that's not a criticism. That may be exactly what is desired for a given instrument in many cases. Just sharing my recent observation.
