This is the LL-526 Falchion Lego Starfighter, created by Mansur Soeleman. The starship comes with a short backstory. The prototype attack craft has implemented stolen Blacktron stealth tech. The unfinished style of this starfighter helps to make it look unique. The Lego MOC has an incredible amount of greebles, right up there with a Star Destroyer. The nose cannon works well and the connections with the Lego steering wheel look smooth. The cylinders are echoed throughout this design. From the nose to the engines. In the end the starfighter looks like the pilot is strapped into a giant jet engine, not sure if it is stealthy but it does look fast.
