what beautiful eyes you have

Her lower body looks pretty damn manly. TBH the reference des linked isn't so amazing! The hips shouldn't be much narrower than the shoulders, often they're wider.
If you simplify a female figure, it's a triangle poiting this way ^
if you simplify a male figure, it's a triangle pointing this way V
most of a woman's weight is usually in the stomach, hips and thighs.
Obviously there's lots of variation, but I'm talking in really general terms.

Curve her collarbone some. When it's dead straight across the line of the shoulder like that it looks pretty manly. It curves down a bit in women.

not a super reference since she's got a shoulder raised but it should give you an idea of what I'm talking about.

Just mess with her overall shape some
again, not the best reference ever because she is kind of muscly and it is AIRBRUSHED LIKE WHOA, but this is something like the shape you want (possibly NSFW because tits)

There's a reason the phrase 'hourglass figure' exists!
The curve should be pretty soft, you've made the shape of her hips kind of harsh.

Sorry if I'm being too vague or something! I don't knooow
