One piece of feedback for you: you might want to study English pronouns. As I mentioned in your story The Girl on the Train, you tend to mix up the male and female pronouns.

The correct pronouns:

He estimates her to be about thirty years old, although her graceful figure gives her about five years less..

That day he dares to go out to board her and unwittingly his glances cross and he is immersed in the air of the tropic that emerges from his pupils..

The correct pronouns:

That day he dares to go out to board her and unwittingly his glances cross and he is immersed in the air of the tropic that emerges from her pupils..

-Just that? -he replied with mischief.

The correct pronouns:

That day he wears a short skirt that highlights the shape of his thighs.

The correct pronouns:

That day she wears a short skirt that highlights the shape of her thighs.

So, for women, you need to use "she," "her," and "hers." For men, it is "he," "him," and "his." I hope that helps!
