If this is a Voyager, that Op looks to be mini-con size, possibly smaller, which explains why they didn't do something about the torso: anything they could do would likely be too breakable.
And he's still the same sizeas the space-shuttle gun, which I forsee people bitching about. This is not a toyline where scale is a major concern, people, and the sooner you get used to that, the happier you'll be.
For some reson, the head reminds me of Rail Racer. For that matter, the chest looks a little bit Rail Racer-y, too. (The train combiner from RiD, in case you need to look it up.
)
The legs? Eh, a little reminiscent of Beas Machines Cheetor, but given that this is a movie-style design, that's par for the course. Not a deal-breaker for me. In general, a nice toy, and it somehow softens the blow of RotF steamrolling the hell out of my beloved Animated toyline and ending the not-as-cool-as-Animated-but-still-pretty-nice Universe line.
(Still, I wish they'd given the shuttle its own robot mode instead of a spring-loaded projectile. I know, I know, budget, but the space shuttle is one of my favorite alt modes.)
