Hi! I have to say that I like all of them ... but what I can see is:
1) Needs a new crop reducing the space from the nose to the right side and maybe lowering the plane a bit in the frame.
2) Might be bad dark, but I would maybe give it a try by lowering the plane a bit on the frame
3) it is an awesome shot!! But please give the plane its tail back! LoL In case you took the picture like that.. I would try an aggressive crop of the nose or maybe just after the end of the wing... but it would be much better with the full plane.
thanks for the comments guys. I took your suggestion Giorgio, and lowered the 1st 2 shots in the frame as much as I could with the space I had left, also fixed a slight red cast on the Herc.
I figured the 3rd was bad motive, it was a hurried shot as I had just arrived and was not set up yet. The full frame shot is blurry. Aside from the crop is the quality ok for the panning shot?
fantastic work on these man... now the 707 might be (not sure about that) still a bit bad cetered cuz of the nose and wing spaces to respective borders... but I think it will go trough. The Herk one seems Ok now... and in the P-3 I would definitely try a crop just after or just before the wing. It's a shame you don't have the complete plane, but you can try some different with what you have got.
