I had some time to fiddle around, to make Version 3 of a Transformers: Construct-Bots gestalt. The first two versions are here.
On the right is Hasbro Transformers Masterpiece Optimus Prime (the later one, based on TakaraTomy’s Transformers Masterpiece MP-10.)
He also has modern articulation. The fists at his elbows can be employed to stop the forearms from being able to turn backwards.
I wanted the arms to extend out further, so I had to use a rather flimsy way and cover them with wings.
From the back.
It’s really hard to describe how I did the waist and back. The waist joint is not that playable, though.
He’s double-jointed at the knees, when most Transformers aren’t (one of my main gripes, as well as feet that can fold either way.)
