The Many Faces of Treadwell

[Dyne]

Personally, I think 327-T needs a new model number, as he doesn't quite have the same design or proportions as a WED-15 (to be honest he looks like a slightly less flimsy design), and he has those shoulder pieces.  But this is Clone Wars, we have to allow for the stylized art.

Fatter so it'd be easier to see when rendered?

Maybe, but I was thinking more of the simplification in the head and of the more anthropomorphic elements of his design, like the existence of the shoulders, and the arms being aligned.
