Thanks everyone for the comments!
Jimmer: Sure no problem! I did in fact hollow out the steps. I did that mainly because it just looked that way in some of the references of the full size X-wing (the shots with JJ Abrams standing next to it). It also kind of adds a bit of dimension to the area too. As for the canopy, this one was also silver originally. All I did was paint a coat of gray over it, and then chipped into it, revealing some of the silver underneath. This was initially by accident as I just wanted it to be gray, but it started to chip some. I kind of like the way it looks so I just chipped into it a bit more! From the references I've seen of the regular light colored X-wings, the canopies look grayish. Good luck with your build! I just received a couple of bandai kits....and the details are mind blowing. I'll start a few new threads for those!
