This is a great landing/wingflap image. Your exposure is good and I like the composition. However, the OOF birds detract from the image and lead the eye away from the pelican. These should be fairly easy to clone out. I would also like a little more headroom. Good work on capturing the action.
Great exposure and sharpness and the low angle is nice.
I do agree with Joel on the OOF birds, but I wouldnt take the time to clone them out, that would take too much time and would be very difficult to do without artifacts.
