Because I'm horrid when it comes to drawing full bodies sometimes and like to draw face shots more than anything lol I wanted to mostly get a good enough idea when it comes to their face for my latest Transformer OC; Dirtbreaker!

Their alt mode is actually based off of one of my top three fav monsters; a Graboid! From Tremors! I recently rewatched the first four and I ADORE them sm and my brain had to mesh my current hyperfixation w/ one of my fave monster moviessss.
There are a few different Transformers that helped when it came to figuring out the face, that I'll say.

They speak only Ancient/Old Cybertronian since they've been around for a very, very, very, very long time, and they have three Minibots who can translate what they're saying - as best the little ones can anyway! They only know what Dirtbreaker is saying b/c they've been around each other for so, so long... The little guys have picked up enough!
