I like the idea! But unfortunately the shading isn't very great. I'd do an edit but my skills don't reach as far as creating a good sword :P. You need to define a light source and shade it in a metal -type of material from there. Check pixelsource for help, it's a really good guide. The blade part itself if awfully plain, and it doesn't give it a metal-type effect. Remember, practice makes perfect!
