I'd had this idea kicking about for a little while. What if Optimus Prime turned into a jet? I planned to make a custom TF of this, but hadn't got around to starting it. However, a recent thread inspired me to get off my butt and attempt it. So, for my first custom I present a literal "Jet Prime": The base figure is the Iron Man 2 crossover jet. I tried to emulate the basic Optimus colour scheme: blue shins, feet and hands; white/silver thighs and gut; with red everywhere else. I went with orange for the missiles (similar to the Energon Axe used in MTMTE pt2). The silver nosecone is meant to be similar to the grille of the truck alt-mode. It's very much a work in progress, but the basic idea should be there. I still have a lot to do, most obviously finding a head. My painting skills also can do with improvement, but as this is my first custom it should only be up from here.
