nice image. however I think you need to change the design between each one way more, rather than just duplicate from the previous and add some bits. Eg the bag has not changed once, there are only two boot variants, her gun belt is the same in all, her hair is the same in each, her upper torso has only three real variations. Give her some strapping, buckles, chunky belts , thin belts, big shoulder pads, a helmet perhaps?
The more variety the more choices you will have for a final design.
