This seems to have taken an age to get this finished, mainly as I was painting it in parallel to a 10 strong squad of Bile Thralls (coming soon), given the similar pallet used. I've always felt that the key to this model was to make the stitching/implants look painfully raw. I don't think I've fully managed it, but the rusty cannon and the prominent tubing colour draw the eye quite a bit so the stitches aren't as much a focus as I'd initially thought.
Don't know how to effectively use this beast yet. He's so slow that in the 25pt games I usually play he barely makes it into a good position. Still a nice big chunk of mini to put on the table though!
