At first glance...
Ethnicity: Brythonian
Height: 5'9"
Build: Svelte, even with lazy posture, she stood at a decent height with lithe bone structure, subtle curvatures and lean, defined muscle.
Hair: Deep brunette, kept in a functional, high ponytail. Some angled locks fall loose to hang over the right side of her face, mostly concealing it.
Eyes: A mid-shade of grey that appeared neither dull nor crystalline, lined in kohl, though the right one commonly had a bandage tied to cover it.
Skin: Lightly tanned, sparsely scarred, and decorated in tattoos from neck to toe - her face and chest the only untouched patches. The monochrome depictions varied from roses and blades, to coats of arms and women far more lovely and noble than she. None seemed particularly nefarious in nature at a glance, though some of those abundant roses seemed to be cover-ups (some more successful than others).

Upon Closer Examination...
 A willowy Brythonian woman with the sure-footed saunter of an over-confident alley cat, Jacqueline (or 'Jack', if you prefer) keeps her chin held high and her steady gaze on the world around her. Clove cigarettes had given her voice a raspen quality and aided the warm, spicy Mashiriqi scent she wore, following in her wake.
  It would be fair to assume she was a swashbuckler or a mercenary; carrying a pair of lithe sheathes alongside satchels of various sizes fastened upon her belt. The buckles of most bags were carelessly left unfastened - clicking in tandem with the lazy sway of her hips. It heralded her presence; a soft, ringing cadence in 3/4 time that varied between cheerful or ominous depending on what street one heard them.
  Her attire boasted neither poverty nor wealth, primarily chosen for function and in decent condition. She opted for natural hues and blacks - a trend of coloring that extended even to the muted burgundy she wore on her lips and the consistent black of her tattoos.
  She had the base features one would struggle to pick out in a line-up of other Brythonian women: Dark hair, mildly tanned skin, eyes of a hue just dark enough to be hard to discern. Not passable as 'youthful', though she had yet to show any signs of aging past laugh lines in her shallow cheeks. She was not particularly curvaceous, boyish, enchanting or repellent.
 However, she wore a myriad of easily-recognizable scars that told tale of some martial (or plainly unpleasant) experiences. Her left brow was disrupted just past its arch by two diagonal scars while her angular nose bore a crook that suggested it had been reset a time or two. Chin-length bangs, parted to the right, attempted to hide the worst of her scarring - though the jagged lines creep past that dark curtain.
 A pair of dulled, silver studs - one slightly smaller than the other - were nestled beneath the left side of her lips, that being the only side to lift when she smiled. Her demeanor was confident in apparent lack of comparison of self to others, quick to laugh, with the lackadaisical calm of someone who bothered themselves with little in way of aspiration.
