It's supposed to be the stare of a jet fighter who's lost control.
The figure obviously needs polishing (mask and left eye are just sketched), problem is i don't know how to cast a realistic/interesting shadow map.
Right now there's no shadow/light, it's totally flat. (image 1)
It would be pointless adding details/polishing the rest of the picture without a coherent shadow/light.
I made in grey scale version (image 2). the blue arrow shows light direction, is that right?
What kind of illumination would make it interesting?
Thanks a lot if you stop by!
