i just noticed bonecrusher's (neck breaker) 2 optional feets. he can have the sides of his scoops become the feet or have tread feet like scavenger's (exgraver) - very nice option.
Hook looks super awesome with his crane but his head sculpt doesn't give me his narcissistic feeling. the other thing would be where are his weapons?(oh, devastator's head isn't shown along with hook either.)
