Study of a Guardian - Art O-Level Final

My Art O-Level final for my IGCSE Arts and Design course. The theme was to draw someone seated with a stick of any sort. He is called a "Bawaab" in Arabic - someone who guards a building and lives there. They're common within the Egyptian culture. It posed as a new challenge for me cuz I had never drawn or painted wrinkles at the time. Nearing the end though, I could draw the man without any references needed.
