In the science fiction series The Expanse, a group of main characters find themselves in possession of the Rocinante. Previously known as the Donnager, a small warship built by the Martian Congressional Republic Navy (MCRN). The Expanse has a bunch of unique spaceship designs, almost all of which are clunky purpose built machines. This Lego version of the Rocinante is created by Kevin J. Walter. It features the grey color scheme used to hide the ships origins. A lot of the little details have been preserved converting it down to this small scale. Including communications gear (Lego walkie-talkies), the various cannons and PDCs (the little Minifigure roller skates add a lot of detail), and the giant engine (the Minifigure hands are a great detail). This Lego build has a lot of creative part use, check out some of those complicated shapes in the hull. A little hard to see as the flat grey appearance hides a lot of the details, as intended.
