Batgirl coloring process

i am fixing some of the lighting in the drawing. i though purple would look great in the eye area. since the drawing will be in the dark. I am also adding a few highlights in today's drawing. So far the eyes was blank.

I am thinking of adding some kind of glowing colour in there. It's not because she will have glowing Eyes but probably because she is using some kind of Technology to see in the dark that is why her eyes glows in the dark. or may be if we build up the story differently, then she actually have super power, and the glowing Eyes are a visible part of That Power. As a vigilante some super power is actually really handy.
