Height: Aver...age? Not a smol but also not really tall for a woman.
Weight: Again I don't know. Curvy build.
Voice: Australian, very pretty. She's generally fairly formal in terms of vocabulary, though she sometimes drops that (she calls Omega a pisshole, it's great).
Posture/Movement: Excellent posture, especially in heels. Swooshy hips. She generally moves with purpose or is still; no nervous energy or nervous tics except when manic THANKS NORFINBURY. She does have a very animated face when she's actually engaged rather than being Ice Queen.
Differences from Canon:The only notable one is that she's taken to wearing her hair french braided over her ears and up to keep it from being an endless collection of unwashed knots.
Scars: Biotic implant on her spine, possibly some scaring from the battle for Earth and that time she got shot (but possibly not, WHO KNOWS, future science.)

EDIT: Model Sheet Turnaround in the Vacuum Sealed Catsuit. Warning: it comes with camel toe because fuck video games sometimes.

EDIT 2: hair something like this but neater; redone every morning.
