Good drawing. Very nice Rendering.
However I found it confusing at first glance, until I realized he was cutting down a foe.
Some constructive criticism: I probaby would've added some more 'blur' to the left side of the blade to denote 'movement' The 'blurred out' foe suggests intense movement, thus making your main character appear oddly static. The key though, is the direction you have the blood splattering. Instead of dripping down, have it mostly all going in the same direction as your sword swing. It will reinforce the power behind his blow. Dripping down gives a feeling of slowness; splattering left or right, gives a feeling of speed. Also, it will keep the viewer's eye in the picture, instead of focusing on the bottom of it. The picture would be better served by cropping it at the point right before the gore starts to get darker. That little act would make mostly all of my criticism vanish!
As one artist trying to advise / encourage another: this is actually a VERY well done piece! Please share more!
