It does look really good and Sabine is a great character... in Rebels.
Unfortunately she was one of the worst adaptations of a character jumping from cartoon to live-action in Star Wars, probably ever. So what could've been/should've been an easy cop is an easy skip.
The figure is just a live action version of the cartoon, so she can be whichever interpretation you want.
I don't mind either way, but live action usually trumps cartoon because I find most Star Wars cartoons tedious to get through since they're usually aimed at a more juvenile audience.
Rebels was a bit more engaging than the likes of The Clone Wars though, owing to the time period and characters. Plus it had less rogering battle droids, and less of those seemingly endless battle scenes to fast forward through.
Taking a cue from Justin's final poses I went for a more passive stance with side eye, primarily because the sculpt is so docile. Plus Shin Hati will eventually be standing to her left giving her the side eye back.
