One of the thumb rule in taking airshow or any airplane shots is not to shoot the bottom of the plane....but shoot when you can see the cockpit and the pilot and the side of the plane, aka...while they are banking...(Photo #2). #1 is the best one of all of them. The Angels and the Thunderbirds are good at this so the aim is to shoot with a cloud background. A good shot on a sunny day will be one that has the flicker of the sun embracing the airplane though sometime this can also be overdone. On a cloudy day, adjust the EV. The best setting is Shutter Priority. You choose the shutter speed and the aperture is taken cared of by the camera. You use the manual setting on static airplanes (on the ground shots) because these guys are very fast on the air and you cannot always catch up with their act.
(BTW, one of the performers in your Forth Worth show this year is our friend -- Julie Clark. She lives in Cameron Park CA.)
Sorry to be critical of your shots...you ask to critique.
