This is the original design on which Sharp was based, with the style updated to be more recent.

Her exposed spinal column was supposed to give her extra flexibility, and it was easier to draw than a plated middle. Most of her joints were exposed, and she had sleeves on her arms and legs to give her a more stylish appearance. Again, her ears and dreads are present, as is the shape of her face. Unlike her brother, she was built for long-distance combat, sniping and the like, while Blunt was built with a heavier, more durable frame and stronger servos that gave him melee brutality.
Back in these days, she was able to talk, and she was to the point and very firm with everyone, not tolerating idle banter in important situations. She wasn't shy in the least, being outgoing and very tolerant of most any environment. Pride was also a character in her original story, something I've carried over, and she befriended the Metroid easily.
