Everyone seemed to enjoy the result, and that was absolutely the goal of the gift - so in that regard it was a true success.
Edit: Since I was already asked separately, yes it's all edible with a few small-but-practical exceptions. The "tiers" (the base and the middle) are foam board wrapped in fondant, and were planned to be that way from the get-go to support the weight of the cake. The cake itself contains 5 chopsticks: two to support the second tier (holding the upper body) and one each for the core of the three arms. The lower half of the body is white cake frosted with vanilla buttercream and wrapped in coffee fondant. The copper balls are all fondant, and the piping is just royal icing. The upper half of the body is sculpted from Rice Krispie Treat that was then covered with fondant and piped with details. The little armor plates and the accessories on the arms are made of sugar candy (gumpaste). The whole thing weighed about 10 pounds. Dassit.
