I haven't been here in a while, but I finished something recently that is one of my favorite builds ever.
I wanted to get something as accurate as I could possibly get, and also something to go with Mike Psiaki's famous X-wing. It uses a limited color palette, because sometimes too many colors on the greeblies gets a little overwhelming, visually. It's based mostly on the film appearances and studio-scale replicas (Master Replicas and fanmade ones). It is a little difficult getting consistent sources because the proportions, detail, and shaping varies from model to model. Even the films themselves seem to be internally inconsistent with regard to cockpit shape, arm width, and gun size. I'm most happy with the cockpit/head area, which was based on some previous builder's breakthroughs of using a particular wedge. Flail's Y-wing was also an inspiration in general, and for the ring around the steering vains. It seats a minifig, but it is very snug.
Thanks for your time.
