I know the goggles need work, but I was more focussing on the figure. I started with a Zbrush base mesh, and used a greeble alpha from google for the head, and a scaly skin alpha across the main mesh. I used the dam standard for the beard and eyebrows by pressing the Alt key to get the reverse marskings, and a rake brush for the slash across the face. In addition to the tech-like greeble on the head, I used some steam gear brushes and such for the gears, bolts and strap .
