That's two different LEGO builders doing their brick versions of a spaceship drawing by a guy named Ben Mauro. I hadn't heard of him but I'm pretty much out of touch with newer designers and illustrators. Mike Mignola is the last new artist I have taken to. Mostly I know guys from the last century. I look back to that stuff I liked 20-30 years ago and revisit that. Ben has a neat spaceship or something like that. Chas Irish came up with the idea to built a ship based on that middle picture and post their work on MOCpages. JD Luse was the other builder. JD's ship is the one on the left. They both came up with different looking ships but you can see they relate to the original. Fun idea.
