Michaelangelo's David Drawing

My older brother challenged myself and my younger to do a drawing contest against each other because he thought it would be nice to have some nice art as decoration for our apartment. He told us we could choose to draw anything we wanted, but it had to be on an 18"x24" piece of paper. I chose to draw this, which was a challenge because I would normally only draw nature and structural settings. I think it turned out nicely and it is currently hanging in the living room.
