Hey! The design itself is pretty cool. As for critique and feedback, for the blade always remember that metal is extremely reflective and will have highlights along it.. what I notice on yours is that its rather thin and its very gray- if you used more blue and white tones and widened it a bit it could look even better c:
Dont be afraid to broaden your horizon- Use fun colors, widen your sprite, and just have fun

To give you a visual as to what i mean i took your image and i edited it into this !
