Ankheg - segmented body

I started work today on the segmented body of my Ankheg model. It is really just a big cylinder that I extruded from the back of the head. After subdivided the lengthwise edges I just positioned the rings along the y-axis where the segment joints were (4 per segment) and shrank the inner two rings to create the joint. Next, I subdivided the lengthwise edges on each segment into 5 rings, then sized each ring to give each segment a rounded look.

Here's a quick render of what's been done so far:
