Hello, here is a piece I’m hoping to turn into a full character soon, but I got carried away on the head, so the body has yet to be conceptualized. :o

nice concept, i specially like the second one…i would only refine a little the hard surfaces, right now they look not so hard, the lines are a little too rought, you would achive a better result using lazy mouse i think. 
Thank you motenai, you are right, I should have tweaked those lines on the helmet area especially, and next time I’m going to post without overdoing the paint overs, Im just recently learning some of the Render options inside of Zbrush4, but barely scratched the surface.
These are very nice!
