Commissioned pencil work

Evening everyone,aside practicing with people's picture,I make lots of commissioned works,this is one of them,a quick one as I sketch with my blending tool first for easy cleaning and the most challenging parts of this work are the cloth tied on her head and the one she wears,it looked completed but to my taste it's so under detailed because I didn't spend enough time on it and the picture was a bit old,done with graphite pencil on cardboard paper,12by16 inches,how does it look? Thanks for checking
