I was planning to add metal shoes, which made her look like she was on stilts. Even though she was already (mostly) customized and prepped, I knew I wouldn't be happy with her if I didn't take the plunge and lengthen her back. I probably could have gone longer, but at the time it looked like a HUGE change.
I started by cutting her in half with a dremel cutting wheel.
I found the path that would cut through the least amount of detail and marked it before making the cut. There is no other reason why I did it on an angle. I wanted to preserve all the original detail so that it blended together without looking like she'd had surgery.
