The wrench position in the third frame is a little out of whack. In the 1st and 4th frames the wrench lines up with the direction of her right hand's knuckles, where as in the 3rd frame it is turned 90 degrees to its original orientation. From the body pose it looks like she is going to swing horizontally yet the wrench is almost vertical.
Dude, it is girly swing. I used myself and mirror as reference
Since the hips and torso are at dramaticaly different angles, I would expect to see some crease lines in the outfit around the waist/lower torso.
If you look attentively - it is corset. Corsets bend on waist, but there are no crease , cause it is thick.
Also it is comic and it was not supposed to achieve anything artistically XD
