Long Charocal Still Life

I drew a long still life charcoal drawing which was done in class and finished at home for 5 hours. It has highlights on the grapes, pyramid,bowl, vase, and the leaf plant with the drapery of the cloth in shadows to make it a dramatic naturalistic look by using light logic in physics. I drew it with cast shadows and highlights on the grapes to make it look realistic like I saw from observation.
I made some changes to make it not look like lines but only value of the objects to look 3 dimensional in CGI films.
