Hey folks, this is my first submission here. It has been awhile since I had drawn a still life. I like to some tips on the workflow/process on working with charcoal, since I have often been confused on what to do with specific charcoal pencils like HB Hard, HB soft, or charcoal vine. I also need some advice on working with glass texture/reflection/lighting. Feel free to suggest could make be improved in this image(please be specific).
