I did these pieces (still unfinished, but it's hanging in my locker now) on the back of my work schedule (for the day).
I imagine the wing-headdress as being made of gold. Done with a two-sided Sharpie.
This woman just had an interesting pose and face, so I tried to replicate it. I wasn't quite satisfied with my first attempt so I drew her again. Then I just doodled. :D
Fine Sharpie on paper.
