Your problem when structuring your stickfigures is that stickfigures are naturally nonsensical, big round heads on stick thin limbs.

Thicken up the torso, space out the legs a bit as well as the arms as you already have, make the head smaller and rely on the depth, the height and length of the jaw and chin to cover the size of what the stickfigure’s head should be. I’ve been revamping my Stickfigure style and structuring lately so if I post about it sometime within my lifetime you could always take inspiration from there / know what I mean.
