Figures in the Landscape- Man on a mission

This is a painting from a photo that one of my art students and good friends let me use. The photo was made on her mission trip, so I call this Man on a Mission.

Man on a Mission 10x12, Oil (C) Dot Courson

 I think it was made in Central America. This guy has these burrows loaded down with sticks, and he's riding one who looks so tired he can barely stand up!
