Alright. I know I'm resurrecting this thread, but with lots of relevant material so I hope it's ok. I've gone through about 4 different types of shoulder pads on this guy at this point, and finally decided to mangle some more tyranid bits. I added detail to the tentacles, and added a lot of barbed wire and chain for detail. I still have some sculpting to do to make it look like it's digging into his skin, but you can get the general idea. I think that the modeling part of this piece is on the final stretch, and I wanted to get some feedback before adding the finishing touches. Like always, crit is welcome. The shoulders still seem weird to me, so if anyone wants to link me to bits that could work better don't hesitate.
