Somewhat incongruous waist and thighs aside, I still kind of prefer this to the ROTB design or even its onscreen model (although the odd bedroom slippers are not great).
I like the proportions of the toy overall (less taper to the torso, especially with the sides and back visually filling in the space a bit), and it's generally a nice take on the idea of a modernized cabover semi Op (When transforming a copy of the SS86 on I was appreciative of seeing some of the touches that informed this design.) The toy could lock together better, though, and it could definitely have had a deeper red.
