I can't fault the detail and focus of the two geese, which is extraordinary. I assume that you tried to crop the shot a little and found that the geese were unfocused at that scale since the wall doesn't add to the idea of the geese in nature. Good DoF with the blurred leafless trees in the background, but there's just a drop too much green in the sky. All and all, a solid 8 out of 10.
