(update in progress)
I used this kit for my Bloodbowl Troll; the body with the strap,the head with a closed mouth, and open hand, and a closed fist. I might have cut a weapon off, but cannot remember.
I was thinking to attach a shoulder pad on one side, to match the rest of my team, but haven’t decided. Also thought about a goblin hanging off of him, climbing up the back, or being thrown/clasped in his hand. I opted out of using the spikes along his spine, but may sculpt something similar.
