Now I know why I like blitzwing so much,he looks like a gundam! Also about tank treads, you won't find any dude. He's not a triple changer in this movie.
Actually the "depth" to his torso and general dynamic angles to his wings and kibble do recall Zeta-style Gundams more than Macross Valks which are typically more flatter and streamlined. The eyes and mouthplate combo also make me think of a Gundam.
I love that Decepticon jet design, complex yet with a defined shape and lots of heavy, non-splintered alt-mode parts.
