Hi Doug,
A bit of criticism from me

The first shot... I don't like it. The background scenery is not interesting, the lighting of the plane is strange and doesn't look realistic, and the angle of view is quite classic. You managed however to create an impression of speed in this shot, which is good

The second shot is much better. The blurries of the ground are not so visible, and the uniform background together with the clouds create a nice contrast with the plane itself, which gets somehow "enhanced". That's very good. I don't like the way the thunder bolt looks, but that's pretty much all.

The last shot is classic but I like this angle of view for the Vulcan. The background scenery is not nice though, it lacks details and the ground textures are blurry. The same exact shot above plain water should look much better, especially if you manage to make the waves look good with just a bit of sun reflections
