Painting by charcoal and brush

Hello Dear friends
This painting was done with the charcoal technique and with a brush. Its size is 50 × 70.
It took about 8 hours.
And in the end it ended with customer satisfaction.
His happiness made me get tired of constantly working on his painting.
What do you think?
I hope you like it.
