Neat!
It is quite nice, and it's immediately obvious you spent a lot of time on this piece. The lighting is interesting, the action is definitely intense, and there is a lot of movement going on.
You could improve the composition by adding complexity to the building in the back and making it follow the perspective imposed by the wire fence; that would probably make the action a lot more dramatic. Depending on what painting software you are using, you could also increase the realism of the light and particles with a couple subtle light tricks (screens/outer glows/overlays in PS) or perhaps motion blur.
If you're feeling like a warrior, you could also add smoke to the scene and textures to the clothes! I would really enjoy seeing you revisit this piece some day, or similar pieces to this one. Keep up the good work!
