Very nice, but i miss scratches and burns in the direction of flight, maybe around some rivets, and vents. This looks now like it never flew, like its was just exhibited in the outside somewhere. BTW. my country still has some of these in service.
Nice! Just as an idea, you could project the BG image on a huge plane(horizontal) so the clouds afar would stand still while the once closer to the plane would move slightly, making it more believable.
