This is my design for Shockwave from my Transformers universe, which goes under the name Invasion until I can think up something more interesting.

The idea was to cross the Slim build and manly chin from his animated incarnation with a more classic aesthetic. His alt mode is a Cybertronian aerial artillery unit, basically a big cannon with wings. His arms are a tad too long, but then again what's transformers without anatomical oddities?

I would have coloured him, but I wasn't sure wat to go with. His regular colours would probably be more imposing, however I think he'd also look funky with a scheme based his Energon/Transtech selves.
