These concept sketches are actually preparation for my Drawing and Composition class’s final project towards the end of the semester. What I want to do is draw a big battle between Kushite and Greek forces, with the Kushites led by their legendary warrior king Memnon. You could call it an illustration of Greek mythology.
Those lines on the Kushite archer’s faces are meant to represent ritual scars. Today scarification is associated with South Sudanese groups, but some ancient Egyptian wall reliefs depict Kushite warriors as having these scars on their foreheads.
