Partly for shading practice, partly for jumping on the Bandwagon.
On a side-note - I thought up this design before Boom.


Her goggles are outfitted with the latest aid in thieving technology - able to evaluate the gross value of just about any object and schematics of a large range of security systems.
Her series hairstyle looks too much like quills to me, so I gave her some bangs and altered it until I felt that it fit her.
Her "skin" only goes a bit past her bosom.
Larger wings that are closer to the correct anatomy
Her outfit is tailor-made. Only the finest of fabrics are suited for a lady of her prestige.
The shirt is zippered close and doesn't have much of a back. (More room for her wings)
Gloves contain technology to aid her in hacking. It isn't always accurate, but it's helped more times than not
Pants legs are cuffed for mobility
Her shoes are made out of a new-age technique that greatly quiets her footsteps. Pair that with her natural ability, and a vast majority would never hear her coming.
The sports tape/bandages/whathaveyou on her boots is to insure a quiet footfall. The ones on her gloves is to prevent them from falling off.
Her bag is just a plain-old messenger bag. Nothing too fancy about that.

I drew her tail in the initial sketch, but I realized that it looked awkward with the wing placement. It was one or the other.
