I didn't imagine Changa in all of that garb. I guess this must be an alternate outfit for him.
I've always pictured him looking like Kale (voiced by Dennis Haysbert from the All State Insurance commercials) from the DreamWorks
animated movie, "Sinbad: Legend of the Seven Seas" but including a leather vest protecting his bare chest and metal bracelets protecting his wrists instead.
"That's enough, Panya...!"
Now that drawing of the Tuareg is close to how I pictured him yet needs work. Mysteriously silent. Robed and only his eyes are shown.
