#1 Looks good, don't see anything wrong with it. Just an old awesome classic bird!
#2 cut the tail off by a hair so that might lead them to being as ass.
#3 Looks good but again that hair of the tail.
And #4 I am just impressed to see you actually edit a few shots. Lookin good buddy.
#1 & #2 are really nice shots, but they may be a bit dark...basing this on my last rejection from JP. #3 looks good but as has been noted, that little bit of stabilizer you cut off may earn you a rejection.
I personally love the two Everts birds, someday I'll make the pilgrimage.
Using a D700 with a Nikon 70-200mm VR lens, shooting RAW, import using bridge (to replace metadata) then edit in photoshop, usually take the exposure up just a touch, lower the black up the clarity by two or three digits and then sharpen the edges and save. to upload them to here i downsized them to 100dpi and lowered there size..
@SDRivers very nice images, some will likely get accepted ... I say CROPPING is a HUGE important point. They love tight crops and neat crops and centering is very important to the screeners. Color Balance is also important as is contrast. They don;t mind the belly/landing gear being totally black.
