Firstly I LOVE his design! The art is perty and I love his clothing style.
I think he has a really well rounded personality. You've explained him really well and I don't have any criticism.
My only questions involve his history. How does he feel about his creator? Does he serve her dutifully? Did he come pre-made with feelings for her? He is, after all, supposed to be her perfect man. Was he made to be a mate or just arm candy? Is he her only patchwork?
With patchworks they seem to have a very strong connection, whether they like it or not, to their creator. Perhaps you could give us a little bit on her or at least his feelings on his 'purpose' to her.
