Several issues here.
Unfortunately, I think you need a complete revamp. I know it sounds mean, but let me post my reasons for saying so:
Composition.
Usually there is a triange of main points to look at. Right now, your sword is pointing down and left, and it makes me look that direction as opposed to looking at the piece. Composition rethink is needed, I believe.
Technique.
Don't outline and fill in colors. It's a typical mistake that a lot of people make, myself included. Block out shading with basic colors first, then add detail. If you tihnk about it, there really are no outlines anywhere; just things defined by change of color. Stole that line from Evileye. I'll quote it here if I find it.
Maybe a demonstration will follow; it depends on my time. I know it's hard to explain composition, so I'll try and demonstrate later.
Keep practicing,
Shrike
