physical characteristics tl;dr meme

Height/Build: 5'8" and military!muscular, despite Bioware only having one female body model. So she looks more like this or this.
Physical Mannerisms: Bioware animations Very straight posture and good balance when upright, but really relaxes sitting down. Right handed. Military stuff - steps off with left foot, walks fast on her own but in line with whoever she's next to. If reaching for a firearm, she instinctively reaches between her shoulderblades rather than to her hip.

Verbal tics: General American accent with the odd more Canadian "eh". Kind of low pitched, often dry toned. Liberal use of military terms. If she's speaking Spanish, her accent's native (mainly Puerto Rican) for, like, food and family words, but goes gringo if she's trying to form a sentence. (She's embarrassed by this so it probably won't happen.)
Voice:

distractions
poetry
drunk and lots of laughing

Clothing Style: Arrives in games in a tight uniform, but eases into more casual clothing. Leans towards long sleeves and pants and covering up the circuitry around strangers. Boots and sneakers, no skirts or dresses (thinks she needs an occasion to wear one).
Tattoos/Piercings/Scars/Metal limbs/etc: Her scars are usually covered by clothes or her hair, but if she's in something sleeveless, there's a newish line along her right shoulder where she broke it. She has glowing green circuitry embedded in her skin and eyes:


Anything else: She's mixed race Latina as per dev comments. Her icons are kind of inconsistent on skintone because ME3 washed her out compared to the first two games - this is her:
