Some sculpting. The medium is Green Stuff - 2-part epoxy putty. I've actually been working on this for a while (very very slowly since sculpting is not my forte). It will eventually be a model of the character "Molly" from William Gibson's Sprawl Trilogy - a cybernetically enhanced mercenary with blades under her fingernails and mirrored lenses surgically grafted over her eyes.
Future additions include huge lenses on the face, 80's rocker-chick shag haircut and of course hands and face. I might actually remove the combat boot and give her cowboy boots instead. The book mentions those somewhere.
