The guy who directed Gurren Lagann and Kill La Kill independently publishes his sketches sometimes. Here's some Transformers stuff he drew. Pretty cool. Didn't know if I should post these in the fanart thread or not, since they ain't mine.
He has a wonderfully intense and kinetic art style. I am curious as to how he'd have drawn TFP Airachnid and Arcee though; given his resume (TTGL, PSG, KLK), they may have been somewhat shameless LOL.

Set up a challenge, and we'll change to overcome it! We'll show you we're more than meets the eye! AUTOBOTS, TRANSFORM AND ROLL OUT! give me yur faaaaaaaaacccccceee"
