Grey in Zbrush

I've found that i'm more of a 3d artist than 2d, so I'm trying to work on marrying the two. This is a really messy Xbrush model, I used my mech model I made as a base(which is why it has no arms and legs). It was meant to be a quick sculpt of me just working out the character... and turned into me fighting with zbrush for about four hours. I'll redo this sometime later now that i have a plan. The super shiny part really showed all the places I couldn't manage to smooth it out.

Anyway, this is Grey, an alien in the robots and racks stuff. He's a grumpy butt.
