Please understand this is constructive criticism. Don't kill me. The thing is, when I see photos of actual weathered rolling stock, the paint does fade, but it doesn't distort and disappear quite like that. I can't even really see the BN logo anymore, or the lettering, and frankly I can't find any example of such a thing in the real world. I can find lettering that has turned half brown and looks a very pale mint green, but the edges are still defined. Maybe concentrate more on rusting up the car, or even applying a very thin green wash to simulate the white paint fading, but not just erase the edges of it like that.
