Quoting Stephan N
A very nice Mech. As always, all pretty consistent. But at the picture looks the G1 Galvatron more Massive, I do not know how to describe it. Muscular somehow.
That was my thinking too, the upper body needs building up more. I am working on version 6 which incorporated a new thigh design, before I post images, I may also retool the chest and widen the shoulders.
Ultimately I want to add a transformation, but at the moment that is impossible.
