Drawing after Michelangelo

I did this drawing after Michelangelo.  I used homemade charcoal on watercolor, toned paper.  I may start selling these copies???  I am learning so much from Michelangelo!!!

This is for sale on etsy:

Charcoal, Wash Drawing, after Frederic Rodrigo Gruger (FR Gruger)

This is the beginning and ending of a copy that I did of after Frederic Rodrigo Gruger.  He would usually start with a light drawing, then wash, and wolff carbon pencil.  I can't find anywhere that still sells a wolf pencil in the grades that he used.  Bummer!!!
