Video games are a great source of inspiration when it comes to building LEGO spaceships, especially the Halo franchise, with a wide variety of orbital, deep space, atmosphere, and ground vehicles from many space-faring species. Marius Herrmann, who has built models from Titanfall 2 and Horizon: Zero Dawn has built a stunning version of the AV-22 Sparrowhawk from Halo Wars.
While this might look like a digital render to some, the source for many of the unusual olive green elements is much more analog. The builder used a very careful application of spray paint to produce the needed parts for this wonderfully detailed craft, and the results speak for themselves, if you ask me. On the more traditional side of things, I especially like the propellers, made from a lattice radar dish plus mini-fig hands and hooks.
Here is even an added bonus, a depiction of the craft in action.
