Here is my favorite. The plane is off the ground, you can see the prop condensation, the lighting is good and I love airplanes.
I like this particular crop, because most of the sky (blah) is gone, and there is a little more space in front of the plane than behind. The plane looks large and powerful. If it were really sharp, it would look great printed large (2ft x 8ft). You might do a white balance on the shadey side of the plane. It is a little blue (cool). Maybe 1/2 way between current white balance and white on the shadey side (does that make sense?).
I like the choppers; but I don't care for them being back-lit (sun behind the subject). Crossing or diagonal light makes the birds look better.
You can get the feeling of motion, by slowing down the shutter, and moving the camera with the bird, as you squeeze the trigger (like tracking with a moving target).
Cold mornings have less mirage, and the cold air magnifies the subject. I'm looking forward to some more of these images. Nice work.
