To be fair to the sculptor, the original sculpt from MW:DA wasn't exactly their finest moment. So he had a pretty daunting task ahead in the first place- make one of the dumpiest-looking Mechs in the line look decent. He may not have been aware that the DA sculpt was enormous for a 40-ton Mech, and went from there with creating this one.
The Galahad was horrible for it's own reasons, but this one may have been doomed from the start.
