I made this at Middle Creek during the Snow Goose migration in March. I'm wondering if the wing position and BG work for you. There is wing/bill separation, it's just not so obvious because of the BG.
1D4, 500f4, 1.4x, 1/1250s, f/8, ISO 400, manual exposure
I like the wing position and despite the BG is busy I like the feel of the image that represents the number of geese. Of course tecs are great as expected. Congrats.
Pose and BG works for me Axel but, if it is possible, I would go for a wider crop with more room at the right to increase the feeling of a flock in the BG and not a confuse pattern of withe and brown. The main subject is very well isolated and that is what counts. :)
