This model is very fond of using sticks for props, but she doesn't seem to be acting out anything in particular. The broomstick doesn't become a spear or paddle or garden rake, she just kind of leans on it or holds it awkwardly. Still it makes for some variety from the models who avoid props altogether. Sometimes the best thing you can do is draw the model, but not the stick and then the empty handed posture might remind you of something and suggest an entirely different action. That's what I eventually did here
Fortunately I had a photo reference for this one. I'm not allowed to share it with you, but I can use it to finish my drawing.
