Sculpted most of the details. I tried foam for the belt and shoulder pads and it worked well.
The headband was plain and boring in reference pictures so I segmented it to be more interesting.
Learned how to sculpt that afro-ish kind of hair texture; Sculpt the final shape of the hair, then use a round tool (like the head of a pin) to make a bunch of small shallow indents in the clay. Keep denting it until you're happy with the texture.
