And this one I was commissioned to draw, although I probably would've gotten round to attempting Soundwave in time, monetary incentive definitely helps :P
I'm at the stage of trying to make the characters at least look accurate before prioritising expressiveness (--not that Soundwave has ever been used to portray much expression)

But an interesting experience trying to draw transformers. Honestly I put it off for so long because I thought I'd combust into flames or something dramatic.
