I like your armored version of this guy better, but all in all this guy is pretty B.A.
I like this because it looks light and not bulky, however, it needs more detail. Perhaps tone up the legs and arms, but not so much it looks bulky like a WOW character. Pretty nice.
Great colors, style, but not really... Active. He does'n look like jumping, more like floating.
Wow this is nice original work it's original and I like your technique.
