If you make the whole canvas larger, you can make the ends of the scissors move outside of the characters silhouette. this will add depth to the image and make them stand out even more.

I cut the scissors out and used a perspective warp to bring them closer to the camera. its a small change but it makes them stand out. I also made the back of the character darker using a multiply layer, the stronger contrast makes the bright metal of the scissors stand out. there may be more you could try with colour and line weight as well but i stuck to what could be changed quickly hope this helps and have fun finding what works
