I like the change in tools, I will very hesitantly say it looks a bike lock right now. I think this image has a lot of potential and I don't want to be a downer type of influence. I might suggest a more profile look at a traditional or old fashion hacksaw that has some magical powers. The view right now is more of a forced perspective, dynamic view while it might be easier for the viewer to understand what it is if the girl is in a pose that would mimic bucking a log with an old wood saw but she's holding a clear side view hacksaw. The pose wouldn't have to change much, just the arms but I think it was a wise choice to change the tool.
