Looking at this again, I just noticed the fire girls right arm. This is a spot where getting some extra reference might help. It's actually a challenging angle to draw that arm from, it's leaning toward us and so it is foreshortened. Then the hand is leaning straight toward us, which can be even more challenging.
I think taking some pics of yourself or a volunteer in this pose could really help (maybe recruit Charles). That being said when working from photos be aware of how a photograph will flatten and distort things.
