Building a Tervigon: Sketchbook Edition

My Tervigon is nearing completion, and here's the sketches I worked with. I wanted this one to look like the one in the book. My next one will be a radical departure. Anyway, having a rough sketch to work with is helpful. I didn't copy it exactly, some details turned out to look fine on paper, but not work out at all in green stuff. I should have the guy completed by Monday, then hopefully painted up by Friday.
