Hey!
Cool sprite you got there! If you want it to be more shinier, you should add a bit more contrast to it, so that the shine sticks out more. Basically make the base colour of it darker and then the lighter shine colour will stick out
Otherwise if it's a light colour on another light colour it all blends together. And in the same way I think it could use some contrast on the handle too, to better make it all pop, so something like this maybe
