Hi,
Thanks for the feedback. Resized and adjusted the edits as follows:
The Hornet:
IMG_4399I've adjusted the hue and saturation of the blue, but the vignetting was caused by the aircraft being up against the smoke and clouds. Did what I could to knock it down, and cropped it some more to bring the aircraft up more.
Snowbirds:
IMG_4818Performed a much tighter crop as requested.
Interstate Cadet:
IMG_4943-2Resized the photo only.
