Chiaroscuro drawing u

Hi hivians, here is part of my series on study of chiairoscro drawing this morning a quick drawing figuring where the actual light is coming from.
I took this drawing along with my friends called @tezzmax and @bobdray
It was actually pretty and challenging in the process creating sharp contracts high light and darkest part of the model.
I started the drawing with blocking form all through the process creating and separating where the light is actually coming from and how it fall on the model was quite interesting . Thanks
