Hey Andrew,
Power - If that's your fezza, can I have a go in it pls
You captured the detail well and I quite lke how the only real colour is the the manifold (at least I assume that's what it is).
Re-Shoot - Liking the way you've crushed the blacks to give it edgy harsh contrast. Works well
Above - Not showing on the thread any-more, but I can click through to flickr.
A couple of suggestions. Bring the shutter speed down to 1/250th if possible, to give you some motion blur at the prop.
Also, the sky just doesn't work. It's a bugger getting planes in flight shots that work well, you just have to wait for the right light. I've got aircraft in flight shots that
just don't work (for me anyway) due to the sky, and then some that have
come out really well due to a different sky / time of the day etc.
Evolve - DK is right about the top corner, I think you could cure it by adding noise selectively in that area, I think it would hide it quite well. Great detail in the new foilage.
