This would be concept art for Juba al-Mauri, one of the characters from my novelette The Sultan of Finback Isle.
Hailing from the mountainous highlands of Morocco, he belongs to an ancient ethnic group in the area known as the Mauri, whose name would evolve into our term “Moorish”. Although he wants more than anything else to help his own decimated people survive in the modern age, his search for profit has brought him into the employment of the story’s antagonist Ibrahim Fawal, a Moroccan-American Chief of Police in Los Angeles who is of Arabic ethnicity and treats Juba with more than a slight dabble of racial prejudice. Also, Juba’s very good with his shotgun and even more so with his scimitar.
