Interesting.
The first thing that sticks out to me is that the lighting makes no sense;the helmet, sword, and arms are lit from the top left, the body and the left (our left) leg are lit from the front, and the other leg is lit from the right. I believe the first thing you could do to improve this piece is add a consistant light source.
The current version is an improvement to the earlier, as you can actually make out some hands now, but the left (his left) arm still gets lost at 1x1...don't quote me, as I know nothing of anatomy, but maybe it's too short
And lastly, I'm slightly annoyed about that vertical line coming from the helmet......what is it, even?
But on the flip side, I think this accurately reflects an rpg style enemy...and I love your base color choice. Keep on pixelling!
