The lines on the blade are very jagged, I would do a quick edit to show you mean if I could. Since I can't, I'll point you to this page because it explains what causes the jaggedness and how to fix it.
Also when you get to work in the colors, I would recommend making the blade very high-contrast to show the glinting of metal, and the handle less so.
