I have to admit, I've been poking a lot of fun at Chickenwing, but he really does look pretty interesting.
Ratchetbot II looks...worse. Every time I see it WORSE. Who thought that deco was okay!?

It really could have been done well if they had gone all out on Dinobot II's deco, I think. Still weird, but it would have looked cohesive.
Skystalker at least has my favorite deco so far icyblues and whites mixed like that are always pleasing to my eyes. However, as with every single Predacon in the line, bar none, he has the same stupid, unimaginative transformation. Easy, easy pass. Plus, those wings look like they won't pose well and will just make it excessively topheavy.
