Pretty much completely agree with everything with Stompy said except I'd be more savage on the robot mode. It looks fat to say the least. The legs accentuate the fatness of hte chest. The wheel panels cover the swords add to this bulkiness that is sorely juxtaposed by skinny legs. The hand sculpt can also look out of place in certain poses because it makes him look like a disfigured/disable bot.

The stowing of the weapons is probably the biggest plus though. Love the way its done. And yes, the lower leg panels are great pieces of innovation.

Alt mode is great, awesome actually, but getting it right is a pain in the tushie.
