Tom, I'll offer a couple of things that maybe are just personal preference but something I see as a bit different than I would have done it. In my mind the patchbox could be tapered a bit more , it likes sort of wide near the rounded portion. Also expanding on what Don said, maybe the wrist/comb transition dish could have been extended a bit further back just until it needed to flatten out for the patchbox lid itself. I think that would look sleeker.
That's really nick picking. I think your work is first class.
