skin tones - non normal colours to make her appear more damaged and not quite human. here without coloured clothes i think she kind of looks like a nurse...so she could develop into having needles and stuff to jab enemies/tresspassers at rather than a knife.
trying out different mask designs, hairstyles, and clothing. and also the possibility of her having leg braces or hand/feet alterations as a result of being reconstructed into robotic form poorly. clothing/mask/etc combinations to come next
