Good job, FTJR.
I found a couple of color shots. Interesting to see the elevators and ailerons are painted silver, a silver with less blue in it than other areas of the skin. In fact I think the aircraft in the 2nd photo is all painted, with a replacement panel on the upper left wing? I think the aircraft just below is bare metal, and the skin takes on a bluish cast, esp. on upper surfaces.
Does your specular value allow a nice broad glare from the tail when the sun is just right, like in the first photo? If not, it might be a little low.
