I have to say, when i first saw the scale comparison i was not favorably impressed. That thing is TALL for a 30 tonner. At least it has decent torso structure quirks, it's going to need them.
After a second look, i have come to believe that the reason is the thinnes of its legs, both frontally and from the sides. it's not going to be an easy mech to leg, and the low volume of the legs means that the rest of its 30 metric tons gets dumped into the torso sections.
