Just a quick little WIP for a sketch of the reference sheet I'd like to make for Syn, my lady-robot character.
Mostly I was just trying to figure out what she looks like without her outer layer of "skin," revealing the mechanics or structure beneath.

Syn was created as a prototype to test a number of biological inspired technologies, and make a human-like machine.
Her skin is made of pliable material laced with layers of nano-machines. The nanites make the skin capable of self-cleaning, colour change and temperature control. The ninites in her skin act collectively as sensors, allowing her to have a keen sense of touch, as well as several other benefits.
Rather than relying on servos or electric motors for mobility (though she does have some) she mostly rigged with artificial muscle, constructed of carbon nano-tubes. This allows her to bend and move in a manner much closer to a living thing than most machines.
Her tail is largely decorative in nature, but the tip of it retracts to reveal a a small series of plugs and adaptors. Her tail is in effectr her power-cord and primary electronic interface device. When her power cells need charging she simply plugs in to the nearest adaptor and enters standby mode until fully charged once again
Her central processing unit is located in her head, like it would be in a human, and was designed specifically in a manner to emulate human thought patterns

I'm still not sure I like the design of er with her outer structure removed, so that will need some work before I begin to finalize her ref sheet. But since I've been slow about posting lately I figured I put this up anyways.
