Another attempt at BIF, applying Birdpix's suggestions.
You should be very pleased with these shots as they are well focused and composed. Are you doing any post processing? It's obvious you were shooting on a very gray day. A little overall increase in exposure and some tweaking of the shadow areas would bring out some more detail.
Thanks for your comments birdpix. Very gray day for sure. The goose pic is straight from the camera. The others had some cropping done and a little PP.
