New Realistic Pencil Drawing Of A Man

Hello everyone @worldofxpilar
Here is my recent realistic drawing that I made.
It is a commissioned piece.

The man's head is not complete in the reference picture so I had to complete it. When doing the sketch, I kept space at the top of the paper so that the remaining part of the head can enter.

I was a bit scared if at the end the drawing won't really look like the person because I have seen the person before in real life and the client did not have any other picture of him to show me, so I don't know how his front hair is like.
I'm glad it turned out very fine and no complain as usual, he loved it.
I hope you like it.

It took about 22 hours to complete this piece.
Size is 20x24 inches.

MATERIALS:
Pelican
General's charcoal
Graphite pencil
