Hmmmm. It depends what you intend the pics to be sky high. Often as not aeroplane pics tend to fit into the category of the " record shot". The first shot is classed as a "candid portrate". The big problem is the red release handle on the canopy, it draws the eye away from the main subject.

When taking pics of any moving object, try and imagine them flying/moving from left to right, the way the western world reads a book. Leave space infront of the subject to move into.

Too much to say in a few words...lots to it that can be improved with a little care and thought.

I could rattle on for hours about photography. I'm a much better photographer than I am an archer..
Nice gliders.
