The piece is called "heretic". I think it was a Mutant Chronicles or something.
I like the casings, and the mottled base color. I wish the face was a bit cleaner, and the skirt striping was different. A more matte protective coating might be good, too.
I like this miniature (sumptin' about girls with big guns! ). Don't much care for the color of the skirt, seems a bit dull, with no shading or blending and overall the mini looks too shiny. Try a dull coat perhaps. I DO like the shell caseings on the ground though. That part of the mini or did you add that?
