Actually having shot a bow I see at least one physical issue that she's bound to learn the hard way; Her bow grip is a bit too powerful first of all. it looks like there's not any room for the shaft and tail to pass cleanly; immediate damage: Cuts from tail. The amount of strength that I presume she possesses for being a hybrid octopus; secondary damage: inertia and plausible string slapping. Though her "forearm" is probably not what would get hit. wonderful piece however.
I agree, the amount of unnecessary tension that she is putting into her grip is going to literilly come back and bit her. Though now that I think about it , I wonder how much actual force can she achieve with octupus arms? And her I am discussing the physical properties of a fictional character yet again -_-
