The Covenant of Primus: Ratchet finds a Quintesson chip in Coldwelder’s head

I didn't have time to create new art recently, but it has been a long time since my last post. And while I'm thinking about writing some new article about MOTU, I thought it would be cool to fill some spots with art I created previously.
This is the first illustration I created for the Transformers: The Covenant of Primus book.
Below, you can also see the pencils.
