Turkish bow decorations

Hello to everyone,this is a bow I made a couple of years ago.I decided to cover the back with silk and to decorate it.The pattern is a personal variation of the hatayi pattern.I didn't mean to make a replica,but I hope it could seem somewhat "authentic".I used copal oleo-resinous varnish and a metallic powder(brass?).Any comment is welcome.I would like to see pictures of decorations on other bows,both replicas or old ones.Thank you.
Bye
